Best headers for stock vtir

[skeptic_]

What do you guys think are the best (value for money) headers for a stock vtir with an audm itr full exhaust? Thanks

[EKVTIR-T]

JDM 98+ 4-1 would be a nice match

[CRXDEL501]

Or just keep the stock ones
Seriously what's the point?

Geez you give shit advice at times ffs

The jdm itr 4-1 is proven to give gains over the stock audm manifold..

Just buy aftermarket headers
Yayyy jdm 4-1 whoopee
Not shit advice, advice to save money if keeping it stock
Don't see a point

Opinions are like arseholes, everyone has one. So sometimes you should learn to accept someone else's opinion.

However I agree with your choice since the OT bought an ITR exhaust, it would be a great combo with the jdm 4-1. Better than the AUDM anyway. However the flange is different so I don't think it'll bolt up.

So then crxdel501 opinion seems much wiser

You must spread sound reputation before giving some to dc2-pwr again :D

OP wants to upgrade,jdm 4-1 makes proven power on his motor and he replys keep stock and whats the point = shit advice

Simple.

[nate92]

Rmf 4-1 headers FTW!

[CRXDEL501]

Rmf 4-1 headers FTW!

Nah man he wants to keep it stock
So ekvti-r is the only opinion that counts

[mocchi]

ebay 421 header to complement your im design
midrange

Simple.

He doesn't want to upgrade, he wants best value for money. Unfortuently $400 for a header and $100 for custom work to fit the header isn't best value for money. Unless the header is cheap and custom work can be done cheaper then my advice is shit.

What I see as best value for money is aftermarket rmf/plm/ header to the stock dc2r exhaust. But then he actually bought the stock ITR exhaust so I'd just keep it stock like crxdel501 has said.

Yeah as far as I am aware jdm 4-1 will not work with audm itr exhaust, didn't Rhys do a thread recently detailing this in detail with photos as well.....

+1 rep Moiz :)

Edit: here is that thread;

No headers, but exhaust lengths are clearly different, jdm headers will be too short

You're a troll.

Thanks for the advice everyone! So does that mean i need to change my cat? or can i stil use the audm itr cat

Yeah man you'd need a jdm cat, but a hiflow cat with an exhaust shop to fit it up will give you slightly better results.

JDM 4-1 headers arn't that bad compared to some aftermarket ones (e.g. DC), but at most areas they are very over priced for 2nd hand.

[skeptic_]

maybe i should clear things up, i have a vtir with an audm itr exhaust and im not sure if the previous owner kept the vtir cat or changed it with the itr cat but anyways i just want the best headers that will accompany my exhaust because for now im happy with the itr 2.25 exhaust. i also plan to change the intake to maybe injen CAI. What do you guys think?

[skeptic_]

thanks moiz! you reckon second hand jdm itr 4-1 headers > brand new say skunk2 alpha 4-2-1 headers?

[skeptic_]

in terms of valve for money?

The AUDM ITR cat is different to the JDM ITR cat that is if you are intrested to buy a jdm 4-1 header. So it'll be a nice stock combo with the jdm 4-1 header because most aftermarket header outlets are 2.5 i believe, so if you do get a 2.5 you won't get the benefits with the stock itr exhaust.

I'd say do abit more research on exhaust, price, sound, what you want to achieve. And in the meantime get an Injen CAI like you want, you will be very happy with it.

Skunk2 alpha is an awesome header but pretty expensive hence you wanted best value for money. Look into RMF headers or the PLM designs, theres a trader here on Ozhonda that sells brand new PLM headers from $500. Here (http://www.ozhonda.com/forum/showthread.php?161360-BYP-Racing-and-Developments-PLM-Headers-K-B-H-and-X-bar!-Pre-order-Special). They have TODA, SMSP etc style headers.

Thanks for that man. So what you're saying is that i cant fit the JDM 4-1 headers to my ITR exhaust due to the different size cats? So even if i did get another aftermarket header like skunk2 alpha, RMF, PLM, it still wouldnt fit with my ITR exhaust unless i change the cat?

Think about it, JDM DC2R's had - JDM 4-1 bolt onto JDM ITR Exhaust. AUDM DC2'Rs had - AUDM 4-1 bolt onto AUDM ITR Exhaust. They are both different in lenth and diameters. (Check out the thread TGW92 posted up and see comparison)

Aftermarket header would be best with aftermarket hiflow cat (What most people do). But if you want to get achieve the best preformance you will then have to change the exhaust. Thats upto you though on what you plan to do :)

[TGW92]

Yeah, the audm headers, cat and exhaust system are all different lengths to the jdm ones, just to make it easy lol :(

So jdm headers will not simply bolt on to audm cat and exhaust (whether vtir or type r) as the jdm headers won't reach the cat.

Even if you go and change to jdm headers and jdm cat it still will not fit, as now the cat will not reach the exhaust.

So in short, jdm headers and cat are shorter, jdm exhaust is longer to accommodate for this.

So it's all audm or all jdm, so your best option is to look at headers made to audm specifications.

It is unnecessarily complicated I know lol

Best advice so far was when Moiz told you to get an injen cai first :) those things make a seriously huge aural difference, with a small power/torque gain to boot

[nate92]

get jdm 4-1 and get a flexi pipe to connect it. any exhaust shop will install it to fit your standard cat if you want to keep it all oem and stock y0~

^ this is your other alternative if you are set on making jdm headers fit audm exhaust :)

[skeptic_]

So pretty much there are no 2.25" jdm cat backs then? because jdm cat conveters are 2.5?

[skeptic_]

so all after market JDM headers and cats are the same as JDM ITR headers and cats in terms of length and sizes?

[ericl33]

lolwut?

i ment same the as OEM JDM ITR headers and cats

[nate92]

JDM ITR headers and cat length is smaller and different to AUDM headers and cat but over lenth of the whole exhaust system is the same length

[EKVTIR-T]

Just to add on for the OP,heres a thread outling the 4-1 swap onto audm if you chose to go that direction

It would be cheaper to not use the jdm cat and source a highflow yourself

[nate92]

^excellent find, thanks!

[TGW92]

yes if headers are made to jdm specifications (eg toda) then they will be the same as jdm itr headers (NOT audm)

as for cats, jdm = 12" long, audm = 18" long as well as the aforementioned differences in width.....

[dougie_504]

Depends on your budget.

XForce isn't bad if you have a lower budget (like $400 max).

I recommend used 5Zigen or Fujitsubo personally.

And I think those PLM headers that BYP are selling look really nice for a cheap price.

[nate92]

jdm 4-1 headers = $400
brand new xforce = $400
2nd Mugen 4-1 = $400

there all pretty much teh same depends on your taste and how much your willin to spend

you get what you pay for.

[EKVTIR-T]

wow nobody else said jdm 4-1

Aww okay thanks for that. Would i be able to keep the audm ITR cat but just change the inlet to 2.5" to bolt on to jdm headers?

Yeah true

[TGW92]

with audm exhaust and cat it would be too short to bolt on to jdm headers, regardless of inlet size. ie the jdm headers won't even reach the cat.

You might be able to get a pipe made up by an exhaust shop to extend the headers to meet the audm cat & exhaust, but I am unsure about this...

You might be better off going jdm cat and have the pipe after the cat, as per this picture posted earlier;

http://i180.photobucket.com/albums/x229/JeffSiReal/DC2R/mini-IMG_2978.jpg

As stated, getting a cat that is made to jdm standard (12" etc.) will be much cheaper than oem honda jdm cat.

A good example is the tegiwa high flow cat converter, on ebay for around $250 :) hope this helped...

Okay thanks for that. Hmm how come I saw a picture of a jdm header next to itr audm header and they were the same length :s

i was planning to get skunk2 alpha headers to suit a skunk2 megapower 2.36" catback but i heard that the headers directly bolt on to catback minus CAT. Does anyone know if this is true? Also what do you guys think of Hytech reps or SMSP reps?

[CRXDEL501]

If your going to go reps, look at plm
You can get them locally now at a good price

any benefits of getting big tube headers over regular tube?
