DC copy SS header impressions

[curik]

Just got this package today. Overall quality is I must say that I'm impressed. Welds and joints are very good, the flex pipe has got an inner sort of layer. Comes with required gaskets and bolts. Weight is 7.1kg. Cost? $350 shipped. Will do install next Friday so stay tuned!

did you get this from ebay?

[mugen88]

Nice one Curik.

Where did you buy from- Ebay?

What brand is it supossed to be and where is it made?

Thanks for sharing.

[curik]

Yeah got it from ebay. The box says Topspeed SS Header. Made in PRC I guess. Here is the review http://tsx.acurazine.com/forums/showthread.php?t=31467

Whats the ebay link?

[aaronng]

Nice. Let us know if the hook matches up with the existing hanger in the Euro.

[ZEi20T]

ohh thats very pretty :)

nice price too! id like to see some isntalled pics.

can i warn you to wipe off ALL fingerprints and grease marks from the headers before you start the engine. it will stain the stainless - ironic yes i know lol - as my S15 manifold was never the same after i pulled it off and put it back on and left all my dirty hand prints all over it

[curik]

black cat, is the hanger in the Euro the same as the TSX? I have no access to have a look at it. Since you are the JTso of ozhonda do you know about it?

[kitbkk]

nice bro,, makes me wanna order one for ma euro too.. i just dont have money for those jdm headers mang..wish i had

[aaronng]

It should be the same as the TSX yes. It's just that some of those running aftermarket headers on tsx.acurazine.com find that the hanger doesn't line up for certain brands (can't remember which) and they end up not using the hanger (they said there were no problems).

[TypeG]

that's cheap
look better than the silverish DC header

so thats exactly where you placed your order? thanks

[curik]

Thats right. SO you are getting one too?

[kitbkk]

maybe bro..
have you fitted it yet?

[TypeG]

i want one as well
hehehe
anyone want to order together to save some shipped?

[kitbkk]

hey Gas, thought you ve got DC ceramic one already? If you want me to order it together count me in!

[curik]

where do you guys go to have your parts installed? I always go to RE Customs in Clayton. But its a bit far from my house so I'm looking for shops closer to the CBD

[mugen88]

Guys, I might join in and give it a go too, count me in.

[curik]

So you guys jump when I jump? What happens if there is no ground? Haha just kidding. Anyway black cat and tomb raider we are not doing any GB yet! I'm installing it sometime this week and review will be done. However I cant do any dynos, no $$!! :(

[TypeG]

yeah let me know the outcome but Dyno was shown on that link which seems not too bad for the price.
I am only ready to buy next month so if anyone want to order it together, just pm me and we talk in MSN since here is no GB

[Gibbo]

curik just install the headers yourself. I have not a lot of mechanical aptitude and i managed to do it myself - there are some great instructions if you do a search on here and the instructions that come with the headers are handy as well, (and the money you save on install means you have more money for further mods )

[curik]

Yeah I wish I could do that too, but I live in an apartment lol!

[hengis]

curik , do u know if the stock cat needs to be replaced if you fit these new headers on the car?

[curik]

Stock cat can be used. No need for a high flow cat at the moment.

[kitbkk]

where do you guys go to have your parts installed? I always go to RE Customs in Clayton. But its a bit far from my house so I'm looking for shops closer to the CBD
hey bro, normally i go to RE customs too but I tried to fit parts myself first, then if i still cant get it done, wait for another day or two, try to figure out, then go to try again and if i still cant do it.. then i call ray/..and by the way im living in an apartment too

[hengis]

thanks curik
don't forget to post review when u get ur header installed.
mine's on its way

[TypeG]

email or PM me guys if anyone want to order next mth
=)

[Atjo]

I just ask the seller about the shipping cost. This is what he said:
"the shipping cost $100.53...for 1set.. if you can buy 3sets,i will give you $50.00 discount..."

If we buy 3sets it will be (($174 + $100.53) x 3) - $50) = $773.59 / 3 = $257.863. So roughly each person pay $257.863 = +/- A$335.23.

TypeG, can you count me in?

[TypeG]

Atjo, if u got a reply from him, u better do that since i havent got any email from him at all

[BusterSonic12]

anyone install this yet?? is everything fine with it, any hissing sound from it?

[curik]

Haha lets all join in the DC copy header community! Kitbkk will help me install this header this weekend.

[BusterSonic12]

remeber to get some sound clips and photos...
I M interested too~!! so how much is it if we group buy?

[Atjo]

Atjo, if u got a reply from him, u better do that since i havent got any email from him at all
You want me to order for you?

[BusterSonic12]

Atjo: how much is it?? now~! how many people getting it?

[Atjo]

Atjo: how much is it?? now~! how many people getting it?
Around $335, can be more or less depending on the currency exchange rate. But that is the price delivered to melbourne. So far only TypeG & me i think, anyone else?

[TypeG]

Kitbkk as well so we got 3 already
maybe Atjo u can ask if any more discount if we got 5 or more

Atjo, u got msn
if yes, add me on lancer_1980@hotmail.com

[kitbkk]

to Curik. yeah bro i cant wait to help you install it lol
to TypeG and Atjo. yeah im in guys,, hey i think myself and TypeG have sent questions to the seller but we got no replies.. so can you do it Atjo? do you mind?

[Atjo]

If we have more than 3 i think we have to pay tax cause the value gonna be more than A$1000, unless if the person willing to separate into 2 shipment. I've added you.

[Atjo]

to Curik. yeah bro i cant wait to help you install it lol

I don't mind to order it for you guys, just let me know when you want me to order it.

[BusterSonic12]

oh... i m thinking of one... but i m in sydney... :(
anyone in sydney interested?

[Pumped]

Im in Newcastle, im pretty interested!
Keen to see how Curik's Turns out :)

[yfin]

Does this header have all the hissing the regular DC Sports header has?

Also is the quality better than the DC Sports one - I know some people have been having problems with the flex pipe.

[curik]

Hey guys who wanna buy this header together. The seller gave me a receipt, and guess what. The receipt said the value of the SS header is $50. No need to worry as the box was plain, no instructions whatsoever included, so the customs wont think that it is something valuable. Yes, and it got inspected and everything went very well. So buying 5 shouldnt mean you will pay for tax. Also, I got the header for U$260 shipped. If you guys buy 5 the seller should be able to give you a price about $230-240 shipped.

[curik]

Lara, it has a flex pipe and it hisses like the DC like what ppl from acura-tsx say. The welding quality is very good and I doubt it will break as SS is stronger than mild steel. Also you wont worry about chipping the header like the ceramic coated DC. After all the dyno proves similar gain to DC and noone has complained about it. I will give my impressions after the install.

[BusterSonic12]

yep... when u get yours install... i will decide then

[Atjo]

Curik, TypeG & kitbkk why don't you guys come to the euro meet on sunday the 20th so we can see how it goes. Curik, you will install it this saturday right?

[curik]

What time and where is it Atjo?

[mugen88]

Hey I'm in for one as well if this is OK!

Why dont we discuss on Sunday at the meet.

Meet is in Doncaster see link for details.

Ok - sounds good. The price is very keen compared to some of the $2000 options out there.

Did anyone notice that Hondatech on their web site don't recommend the DC Sports header for the CL9 - does anyone know why?

[curik]

One reason is Peekay said the ECU is tuned for hondatech products, so using aftermarket parts might not give you the power they claimed. Secondly, being Australian is what we need, and thirdly it gives them advantage in competing with other headers.

It was actually more of a general statement by Hondatech rather than specific to the flash that is why I am curious. Source is post 3 here (http://www.hondatech.com.au/forum/showthread.php?t=230):

...

These engines benefit greatly from 6 major modifications…. These are

1 a Nice free flowing Intake

2 a Nice free flowing large Exhaust

3 a Nice Free Flowing larger primary and long collector header, Cheaper headers such as DCsports are NOT recommended

4 K20 Variable 50Degree Cam Gear

5 Large K20 Cams

6 Tuning Tuning and more Tuning with Hondata

[curik]

Lol, cheaper headers. So TODA or Maxim or Mugen is recommended then?

[yfin]

Lol, cheaper headers. So TODA or Maxim or Mugen is recommended then?
I don't know what they are recommending from that comment. A bit unfair to say "cheaper headers" - as new products are released all the time.

As long as this option is reliable and decent quality (unlike some ceramic DC headers), and it gives a noticeable gain - it sounds good to me. Especially for $350.

Look forward to your review. :thumbsup:

[Tobster]

I would suggest that it comes down to the nature of the headers. You get two sorts of header: one with shorter primaries, which boosts lower-mid range, or you get race headers with longer primaries which boost the upper range -- and generally result in greater peak power.

Things like reflashes are sold on peak power gains -- and thus maximum peak power won't be achieved with the first style of header (like the DC and Comptech).

Peak power isn't everything -- unless you constantly drive around in the upper part of the rev range. :)

I'm interested to hear what this SS header is like, and would think that it's weakest part may be the flex joint. However, if it is a dodgy flex joint, assuming the fit and build quality are all fine, you'd probably still be better buying this header and getting an exhaust shop to replace the flex joint, than get a custom header made from scratch.

[ZEi20T]

dont forget they can vary with 4-1 and 4-2-1 confiugurations :)

[EuroAccord13]

dont forget they can vary with 4-1 and 4-2-1 confiugurations :)

4-1 configurations are for the high end powerband, the Euro doesn't have the high RPM band to go with it so a 4-2-1 configuration for mid range power is recommended...

[Suntzu]

I hope Hondata and their accessories arent tuned for more power. I want a fatter midrange with more torque and flexibility not a token 20kw at 6800 rpm. I dont rev the shit out of my car in daily driving surprisingly enough.....

[curik]

Just installed the header with kitbkk. Thanks to him and his girl-friend the install was easy and straightforward if you got the right tools. A breaker bar is a must, and long ratchet too. Apart from that just get 2 jackstands and a jack. Dont forget sockets too. Should take about 1 hour.

Ok lets get moved on, what I noticed at first is there is more low end torque. Taking off with my heavy 19" rims required less rpm and the engine just pulls out more power! And with some low end torque loss because of the Injen CAI, now i feel that my car have just gained that low end torque. This is just my butt dyno and I havent had a chance to WOT and redline it, but looking at the dyno sheet from acura-tsx, the gain is true. I will post later about fuel consumption.

Oh, and about the hiss, it happens when you apply the throttle, gradually increasing as you go to WOT, but coupled with the Injen, it doesnt bother me at all, it's not loud or annoying. Idle and cruising do not produce any hisses.

[h1coupe]

I´ve had mine installed for a few weeks now, and the only thing I have to complain about is that there is more vibration in the car, you can feel it more in the steering wheel and in the seat at idle. nothing bad but it is there.
other then that the quality seems fine, the hissing doesn´t bother me at all(I actually think it´s kinda cool) and the car is more responsive, I can´t pinpoint it but it´s kinda peppier all around!
haven´t dynoed it or went to the track after install so no number yet.

[BusterSonic12]

damn... this sound good~!! yummy i want one :(
wait for hondata's first :P

[yfin]

Hmmm, sounds like there is a gain but I think I will pass. Don't want hissing or vibrations, don't want to lay out the money for race headers either. The gains through the rev range with ECU tuning look good enough for me to not need headers.

[aaronng]

Did the hanger line up with the rubber on the Euro? Sounds like the flex pipe design was also copied over from the DC header, hence the hissing and vibration. Expensive headers like the Maxim works header have 4 flex pipes to minimise vibration.

[curik]

there is no vibration, and flex pipe is not something used to reduce vibration, it is mainly to allow flex between the exhaust and the engine. I like the hissing sound since it sounds "enginey" instead of something leaking, and since there is CAI I could barely hear it. The rubber hanger fits the header since it is elastic to begin with. Just my 2 fur.

[kitbkk]

I couldnt notice any vibration from sitting in Curik's car either.. The header is very good enough to make me going to buy it on ebay now... so Atjo, no need to order it for me any more.,,Im ordering it myself now,, thanks

hey Atjo,
I have already ordered mine today.. mine cost $300us ..roughly about $390Aud.. might be the currency different..damn

[Chris_F]

its funny that the copy of the DC header may actually be higher quality than the product released by DC. then again the people responsible for copying it had no R&D costs. I personally wouldnt be supporting a knock off manafacturer. But if it works it works i guess

[curik]

Yup F you are right. It's the same reason why people buy replica wheels and bodykits.

Oops, I read yfins post instead. Scratch the vibration. :)

[curik]

OMG, nice paintjob blk cat! How much did it cost you?

[yfin]

you chaps who are ordering - please let us know what you think, in particular whether there are any vibrations. So what is the cause of h1coupe's vibration?

By the way, has anyone inquired as to the price of shipping by surface? This header might be just under $300AUD by surface.

[h1coupe]

I should explain a little better the vibration I speak off. it´s not there all the time, it´s kinda hard to explain it comes when the car is cold and I drive off befor it heats up, when I step on the gas there is this vibration that was not before. it also comes sometimes when it´s fully heated up, when I come to think of it, it only comes when I step on the gas initially it´s like a small hesitation and a shake or a vibration. you probably have felt the hesitation in the dbw, you might say that my feeling is that it exagerates that hesitation, there is not more hesitation just the shake makes you feel the hesitation?

well it´s hard to explain and should not be the reason why you shouldn´t buy the header, it´s great bang for the buck. and I couldn´t be happier with the purchase:)

[JasonGilholme]

Is your car Auto or Man?? Could be the transmission hesitating/vibrating??

Sounds like a good header. especially for $350!!!

Anyone know if the make them for a del sol/civic???

I find there's a bit of vibration low down in the stock car, which I think is just due to resonance in the exhaust system (lots of exhaust sound clips have that real boom right down low) -- this resonance may have been somewhat increased by the header. Not having heard or felt it -- but that would be my guess.

[Tobster]

Thanks to him and his girl-friend the install was easy and straightforward if you got the right tools.
I presume therefore that everything was the right length and the ports and bolts all lined up fine?

There have have been few stories where headers that were supposedly bolt-on, didn't quite fit and required a fair amount of fiddling...

[BusterSonic12]

anyone installed this yet?? any sound we can hear?

[curik]

yep everything fits nicely, no problems whatsoever.

[aaronng]

yep everything fits nicely, no problems whatsoever.
Get a video camera, take a vid, convert the audio part to mp3, and post it up!

[curik]

have you driven in a sp23 before? its a louder version of that engine revving at about 3000 rpm. Now I have started to like the sound, like it is a property of a NA engine. I'll get a shotgun, tie the cat up, convert it into a chicken, and shoot it up! Lol jk

[h1coupe]

my install went like a charm, everything lined up perfect and no problems at all:)

[kitbkk]

installed mine last night. it was very straight forward, everything went perfectly. the quality of the header is great. well gotta love the colour of the header after the test drive, the burnt stanless colour makes me so happy. the power gain is noticeable, especially in the low end. hissing sound is great too. its not crazy loud but just a cool hissing sound. I tried to take of at the red light about at 3.4k-4k rpm and the wheels were freeing more than with the stock header. it makes me wanna finish my assignment now and go to drive my euro again lol. the best bang for buck header and very good quality guys, its not gonna disapoint you at all.

[curik]

time to update your signature!

Curik, are you located in Sydney or Melb? I want to see hear and feel the headers. :)

[euro77]

in melb? I'll hear it for you aaron :D

[curik]

No! go away you limited edition cursed 8 ball. Haha just kidding. I must emphasize that if you like the quietness of the current car, you will notice that the engine is a bit louder in any rpm range. But the good thing is, the well insulated euro means the sound from inside the cabin is still quiet as stock, well until you put more than 1/2 throttle. We are youngsters, we WILL trade quietness for power, am I right?

[aaronng]

in melb? I'll hear it for you aaron :D
Do it! And take vids. Hehehhe

bumping up an old thread
i installed the MAXIM WORKS header for me euro and i too get this HISS sound
personally i find it annoying because it hisses thru all gears from 3K onwards and depending on how much pressure u apply on the throttle
30% onwards, hisses. i dont like it
any way to remedy this?

[curik]

It is a common problem with flex pipes. You can eliminate the hissing sound by changing the flex pipe with a double layered one I guess, there is a thread about it on acura-tsx. I personally like the hissing sound so I do nothing about it.

[TypeG]

shit i thought it was a quality problem and sounds like $300 and $2k header as well have the same issue..... thx for letting us know as your words save me $1k+ to change a JDM one =)

[stephen8512]

oh no dont get me wrong i have no regrets buying the maxims
its just the hissing thats annoying me
i can get used to it but just wondering if there was a remedy.
quality of maxims is second to none and the age old saying "you get what you pay for" holds true

wonder if he has the same probs?

ahh was waitin on u to reply curik cuz ur PM box was full
how are u finding the hiss?

[curik]

not a problem at all. I have stock exhaust and cat, so it is more noticeable than if you have aftermarket exhaust system. Of course the car is not as quiet as stock but since i have Injen and exhaust (soon), I am actually enjoying the sound

[mugen88]

Check with Chris F, he will be a better judge on the hissing sound for the maxim.

I hav the same header as Curik and the hissing can be annoying I must admit.

mate, the sound is totally normal - mine make the same noise :thumbsup:

unlike some exhaust manifolds on the market the maxim-works header has internally braided flex pipes so they don't disrupt the airflow (as seen in the pics there's 4 of them) and they cause a slight hissing sound. Also because that header is equal length it makes a slight sucking/wind rushing noise as each successive exhaust pulse pushes the other etc.

(information based on my conversations with the guys at centrax about this header)

No matter how the flex pipes located, the noise are there. No matter how much the header cost, the noise are there (JDM, DC, chinamade). Are there any way to improved? I never have any deader with this kind of weird noise.

I think your hissing sound will not be loud because of your intake, metalcat & exhaust sounds. Buddyclub exhaust is a bit loud so i think you won't really hear the hissing. I get used to it so it's fine for me :)

[Pumped]

Yea my exhaust does make a bit of noise, i dont mind if the noise isnt to intrusive, dont mind a little bit of hissing :)
If i did i wouldnt modify the exhaust i guess!

i'll see how it goes :) Thanks

[TypeG]

I think your hissing sound will not be loud because of your intake, metalcat & exhaust sounds. Buddyclub exhaust is a bit loud so i think you won't really hear the hissing. I get used to it so it's fine for me :)

Actually the noise in from INSIDE the car which is the problem. with my set up, after i close all the window, i cant hear anything exhuast and intake sound unless i push over 3000rpm. Now, i hear every single hissing sound INSIDE the car. Do a test drive and see what the installer can suggest to remove those noise.

[Chris_F]

No matter how the flex pipes located, the noise are there. No matter how much the header cost, the noise are there (JDM, DC, chinamade). Are there any way to improved? I never have any deader with this kind of weird noise.

I think with the DC header it would be possible to replace the single flex pipe at the collector with an internally braided/smoothed one to reduce the noise. Currently the cheaper headers have flex pipes with internal ribs which are a bit lourder. Have any of the headers you've had in the past had a flex pipe or been of an equal length runner design?

With the b, h and d series etc. flex pipes aren't really required at all because the header is located at the front of the engine and is subject to less stresses than the more cramped header on a k-series (located at the rear).

When i had a stock exhaust and intake the hissing of the maxim works header was noticeable but with relatively loud intake and exhaust it's not so bad anymore - and i like the unique note it gives the car.

so in short - the his is most likely here to stay unless you can find a header that has no flex pipes what-so-ever :p

[TypeG]

internally braided/smoothed one?
hm..... i will ask my mechanic to see if it is possible then
coz somehow it sounds like those old crap car now with leaking somewhere

I'm not sure exactly how it is smoothed on the inside but i think it looks like the outside of the flex pipe as compared to the ribbed piping i know the dc sport has.

yea maybe ask an exhaust shop or something aout the different types of flex pipes becuase your current one is making too much hissing noise for your liking.

good luck with it anyway.

hows the ETD goin?

[TypeG]

lol
i am going to install and fix everything next week
dun worry chris

[Chris_F]

haha damnit I'm hanging out to see if it fits *waits patiently*

[Pumped]

Got mine on, The sounds certainly different, sounds a little like its leaking, Dont mind it though, its not to loud

I can live with, at least for now

yes.. like leaking
just feel weird when someone hear.... a 06 Euro leaking? :p

[EuroAccord13]

The whistling comes from the ribbed internals in the flexpipe, I've just changed the flex pipe on my DC Sports Headers to this "double walled" constructed flex pipe, took the whistling out... my exhaust has gone quieter but the tone is deeper now... ZERO whistle :D

:( it does a bit, "that brand new honda has a hole in the exhaust" :) :p

[Suntzu]

Sorry to dig up an old thread but I was wondering what the long term verdict was on these copy headers?

Also wondering where you can get them in australia or do i ebay them from the USA?

cheers

[E-Gene]

The link is over a year old, anyone can point me to the headers that this thread was talking about on Ebay?

[curik]

only ebay usa sell them, and some sellers are selling them for US100 + shipping should be about 80. well worth the money

[Suntzu]

Any way of telling which ones are the DC copies as seen here? I saw three different EBAY sellers with stock that looks very similar. see http://search.ebay.com.au/search/search.dll?from=R40&_trksid=m37&satitle=tsx+header&category0=

Very affordable at the moment too.

[TypeG]

say no to your brand new Euro SPorts
i prefer to drive without it

[Suntzu]

say no to your brand new Euro SPorts
i prefer to drive without it

So your not recommending the ebay ones? What do you think would be a better buy?

[E-Gene]

say no to your brand new Euro SPorts
i prefer to drive without it

So no headers at all or just no to these copy ones?

[sodaz]

I'd spend a bit more and get something like the Comptech headers. At least you'll know that it's made properly.

[kitbkk]

^but comptech is out of business. u will be lucky if u can find one.
I dont wanna get those JDM ones coz that means ill have to get a new cat which I have already got RT cat.

[sodaz]

^but comptech is out of business. u will be lucky if u can find one.

I just read that they are back in business, under new management so i don't think it'll be a problem finding one.

^oh thats a great info man. :thumbsup:

[BusterSonic12]

[kitbkk]

umm haha nah. i meant i might change it to Comptech header and keep the RT cat. Is there any other headers available at the moment that has same lenght as stock one? apart from DC sports, DC copy, Comptech?

[Suntzu]

So what the main issue witht he porper DC sports and their copies?

Is it the hissing or the fitting and performance? Can it be resolved?

Any happy owners about?

Keen for comments.

The DC sports header has a tendency to crack and it also hisses. The hissing part can be fixed by replacing the flex pipe with a custom made pipe. Performance wise there's nothing wrong with it, performs about the same as the Comptech headers.

[kitbkk]

yeah I agree with Sodaz's post. mine doesnt have any problems at all though. performance wise its a good header. Im just a lil bit sick of the hissing noise. I agree it is very bang for bucks header.

[BusterSonic12]

is it like hissing 24/7 while u driving? or is it more like a bov sound cos i heard that on the maxim header,
u get a bov kinda sound.

[kitbkk]

with mine, i can only notice it when its idling and decelerating. its anoying me when im waiting for the car to warm up while listening to music.

[Suntzu]

Heres the one im looking at. Its a DC header Stainless Steel copy

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&sspagename=ADME%3AL%3ARTQ%3AAU%3A1&viewitem=&item=300117177113

could be a topspeed not sure but looks the goods.

[kitbkk]

from looking at the pics, it looks identical to what i have. gatta wait for Curik to confirm whether its topspeed coz he just got his 2nd one lol.

[aaronng]

Why did he get a 2nd one?

[kitbkk]

his A-pipe was bent due to accident last year. then i helped him putting the new A-pipe to the old one.

[TypeG]

performance wise, it is not as smooth as well. try a JDM one and u will notice how smooth the car and the sound compare to this one.

[Suntzu]

My ebay contact tells me that it is a "TOPSPEED" unit. Based on the DC Sports header. Hmm tempted.

Just not sure where to go up for this. Not gunna speed $1000 on a header..

[kitbkk]

Yeah JDM header should be heaps better in terms of quality and performance wise, but again, my RT cat will have to go and it is expensive.
Im waiting for Comptech hehe.

[aaronng]

The Topspeed header IS the DC Sports copy SS header. You get what you pay for. Performance is only as good as a DC Sports and because it's a copy, you also get the flex pipe cracking problem that the DC Sports has.

[Suntzu]

Bugger. Looks like hte comptech is a better buy then. Any ideas when these will be available?

[kitbkk]

i heard its gonna take them about a month until they r fully back.

[BusterSonic12]

can't u get comptech headers on ebay anymore?

[TypeG]

Not at the moment.

i will think about them when they are back on sale or a JDM one.

comptech = $700, dc copy = $250. Stick with the dc copy as the gain is about the same, I have it for more than a year with no problems whatsoever apart from the hissing sound.

i will see how my suspension goes, then decide on headers since i got intake and ecu and exhaust, wanna complete it ya

[Suntzu]

Man theres a lot of conflicting views about each header eh? Hard decision. Might sit on it and see what comptech do..

[BusterSonic12]

anyone tried the jdm ones??
i see only people go for maxim and mugen, but anyone else tried others? like toda

[curik]

TypeG had the toda. Basically since noone here has a header with the engine internally done up yet(ecu, cams, etc), any header will produce only a small gain in power. So unless if you are going to invest on internal mods or just wanna be a JDM freak, go for the expensive ones. But if you are just looking for a mild gain without caring about bling, the dc copy one will do just as fine as the expensive ones.

it is not about being JDM freak or whatever but the SS DC is actually nearly no gain. Never feel the different until I got my toda in. So so so much smoother in sound and performance wise. not sure about the gain but it certainly feel the engine run a lot smoother.

u had a toda O.o didn't u have a mugen as well then? or was it just toda headers with mugen intake?

toda header's around $1500
maxim $2000
mugen *dunno
only can think of these 3 headers for jdm

[TypeG]

maxim only cost the same as toda actually (in HK) so you can get them when u are in HK

mugen cost $2500+ as it come with the cat as well and is a lot lighter than toda and maxim

[tony1234]

There must be reasons why there's such a price difference.You usually get what you pay for.:)

[TypeG]

not sure as well but it is the fact

[curik]

did you install the metal cat when putting the TODA header on? That could be the source of extra power. Sound wise the toda is much better, but performance is a higher priority.

[curik]

Agree, you get the quality and the brand, but not really for performance. A ghetto airbox mod can perform as well as the mugen airbox. hint: a cat :p

[aaronng]

Maxim headers sound more quiet than the Toda. Toda sounds like your car has a supercharger (whining sound).

[sodaz]

The Toda header is not a perfect fit for the Euro right? Do you need to replace the cat with the Euro R one?

[kitbkk]

^thats right.
you either have to get a jdm cat or metal cat cut and welded to make fit.

[sodaz]

^thats right.

Yeah just what i thought. Not an ideal setup imo.

[kitbkk]

I was searching on the us forums and heard Feel's is making header for K24.
anyone came across it? i think it might fit without chaning to JDM cat. But I just couldnt see any links/ couldnt google it though.

[aaronng]

All the JDM headers meant for the JDM Accord require either a JDM or aftermarket shorter cat.

I visited Feels workshop and here is a couple of shots I took of the Feels header when I was in Tokyo earlier this year. Looking at it closer I think it was a rebadged Maxim works one as it is similar in price.

http://img248.imageshack.us/img248/105/feel1nt1.jpg
http://img511.imageshack.us/img511/4738/feel2ey5.jpg

I have tried the DC S/S copy and for what you pay its ok and does give you a definate change in performance. I also have the Toda header atm and it is a different design to the DC/Comptech ones but works very smoothly with a custom after market hiflo cat. However these are expensive and depends what yr end objective is.

I noticed with all headers (JDM/US) that there is a hissing sound from the flex joint. The flex joint can be changed if you think it is annoying. Also depending what you have or start with the header,cat, exhaust combo will change the note of yr exhaust as I have found out. Not necessarily for the better sometimes.

[stephen8512]

that feels one IS the maxim works headers. It is just rebadged. That is exactly the same as the header I currently have. As you can see, it is quality and it's an artwork in itself. hissing is not as loud compared to a DC ceramic 2 piece as I have sat in both euros (mine and friends with a DC sports ceramic header installed) and the maxim works/feels header is by far a lot quieter at WOT. Even when ur just normally driving/cruising, with the MAXIM/FEELS header, there is next to NO hiss, but i found that with the DC there is still some noticeable hissing noise

with all that said, the hissing is something u just get used to. At first its a bit strange but after a while you dont even notice it.

[ALN]

Doesn't the MAXIM header creates more hiss since there are 4 flex joints.

[Suntzu]

How expensive is this unit. Its looks fantastic.

[aaronng]

Maxim's flex joints are different to the DC sports flex joint. Maxim uses double walled braided joints, while the DC uses an accordion pipe flex joint. Maxim's joint is better because it is smoother than an accordion pipe, so there is less hiss, plus there are 4 flex joints instead of 1, so there will be less hissing when driving normally.

[mugen88]

The DC Sports and Comptech ones are cheap simple street headers. You gain little but they are cheap. Jtune are more like Toda headers with very long primaries, more like the ones in race cars. Of course, that's why they cost 4-5x the price, because of the design and tuning that goes into it.

how much did it cost you, and did it get rid of the hiss?

well.. i went and got my flex pipe replaced.
I didnt mind the hiss, but i had ran something rather large over and it destroyed the flex pipe and i had a nasty exahust leak.

I went for the dual braided flex pipe, no hiss at all. Sounds great, cost me $190 at Hi Tech mufflers in darlinghurst.

I called around, liverpool exhaust west side mufflers etc, and they all wanted $120 for a single braided flex pipe.

Dunno if the price i paid was a bit rich, but hey, im satisfied.

hey felix, these are 2 different items.. any thoughts on both of them.. ?

[aaronng]

DC Sports is the original. It uses mild steel coated with ceramic to prevent rusting. The stainless steel T304 header is a copy of the DC Sports.

[doosra]

thanks aarong.. what do you recommend.. ?

i'm thinking the stainless steel wheel purely on price...

[aaronng]

thanks aarong.. what do you recommend.. ?

i'm thinking the stainless steel wheel purely on price...

I have the stainless steel one and I had 2 problems with it.
1) The flange between the 2 halves was not flat, causing the exhaust gas to leak and burn through the gasket.
2) The flexpipe cracked after 6 months.

So if you do choose to buy that, put on a lot of copper high temperature sensor-safe liquid gasket on any side of the gasket coming into contact with the header flange (so don't put it on the side which meets the exhaust ports). Also, change the flex pipe to a double braided one straight away for about $120-150.

Nothing is ever truly cheap.

[doosra]

damn...

do you still have it on ur car.. ? what are your thoughts in terms of power and sound.. ?

[aaronng]

do you still have it on ur car.. ? what are your thoughts in terms of power and sound.. ?
No difference in power. There was an improvement in mid range response. Sound, the leaking header sound is crap. With the double braided flexpipe, there is a slight ringing sound when you rev it.

Back on topic. LOL

[Suntzu]

I did Fujita Intake and Header at the same time. Mine is topspeed not OBX and yes I replaced the Flexpipe with a double braided after one year.

I Definately noticed a big improvement doing the intake and header at the same time. About as much as the Jtune flash itself. It revved harder and the engine felt free to unload. Now with the RBC and the 300 Cell cat its ultra responsive and flexible. I do think the header plus fujita make the biggest difference and for the cost its the single most worth while mod. I think my Topspeed and futjita landed was $550 aud. I could'nt justify the extra $1200 for the toda even though I wanted it of course.

I need an exhaust though.

On a side note aaronng: Ive been around a bit work wise and I have also worked for a big amercian company here, they are just trying to screw you, if you performance is good then you are valued and they are not respecting you. Forget what they say about the economy if you are good and your skills are in demand( whatever they may be) simply get another job and walk. Forget this financial crisis red herring, work still needs to be done, good people are hard to get at any time. This is why i started my own company 8 years ago due to this type of BS attitude to good workers...

I just installed the topspeed header but there is a slight ringing sound when the engine is rev'd rather than a hiss...not 100% sure. Could this be due to a leak somewhere?

Do you smell exhaust fumes in the engine bay or where the windscreen plastic cowl is? If you do, check if you used liquid gasket. You should use high temperature liquid gasket where the gasket meets the flanges of the topspeed header because it might not be 100% flat. The cat flange and engine head side don't need liquid gasket because they are very flat.

If there is no exhaust fume smell, then it is the sound of the flex pipe.

Thanks Aaron! I will go and check it out now. Another question, if you use the liquid gasket do you still need the gaskets supplied with the headers? Is it better to use both?

[aaronng]

Thanks Aaron! I will go and check it out now. Another question, if you use the liquid gasket do you still need the gaskets supplied with the headers? Is it better to use both?

Yes, you put a line of liquid gasket around the exhaust hole shape on the supplied gasket and then put it on the header. It might be a good idea to use liquid gasket on the cat side of the supplied gasket as well, but you don't really need it on the engine head side.

It will reduce the sound of the ringing if there was a leak, but it won't eliminate it because the Topspeed header's accordion flexpipe design has an inherent ringing sound.
