Go buy an american header.
u probably get between 5-10kws at the wheels and depending on what type of material. it will cost mayb a couple hundred bucks
after alot of debate about this in the past the best bang for buck 4-2-1 seems to be X-force.
the best 4-2-1 with plenty to $pend is toda.
however, there are many different opinions out there..
smsp mild steel header. check out the dyno plots on honda-tech.
hey.Quote:

ummm. i think i might go for edelbrock 4-2-1 one peice header, they claim a 9kw gain with out tunning
how much? and who are you sourcing them thru?Quote:

how much are those headers bro?Quote:

Just one mans humble opinion
best bang for buck imo is xforce, but anything is better than MOST stock honda exhaust manifolds.
best header definately for d-series engines in auz.
any one heard or Hytech i saw some dyno test on a B16a and power went from stock manifold 138hp to 189hp with the hytech header its unbeliveble!!!! they cost round 1350 US dollars but

HyTech Exhaust - TEST SET 01
At this point, you've already seen the graph on the previous page, and you've probably already done the math. Yes - we're showing a 51.1hp increase. Yes, that's highly unlikely and it made everyone... uncomfortable. We have to note that the HyTech unit is marketed as a "racing" header and will not fit with the power steering and air conditioning compressor intact; these were removed for our testing of the header. Still, our test procedure stayed the same, our test platform stayed the same, and the multiple runs we did were all repeatable to within 3 horsepower of each other, with power curves following the same lines each time. Like the other headers, the HyTech unit increased low-end torque production to such a point as to negate the effects of the "pre-VTEC" dip in the powerband, and it also straightened the graph to make the powerband more linear after that point. Like the other headers, the standard test procedure was followed, with the same extension pipe mounted onto the header. DISCLOSURE: The pipe was provided to us by HyTech as they were concerned about the possibility of a loss of power due to the relatively short runner length from the collector to the header's exhaust gas exit point. Now, one could easily conjecture that the pipe benefited HyTech the most because they designed it, and that would be true. However, that fact doesn't prove that this was an act of collusion; it rather suggests that HyTech might know a little something about header design that we don't know - hence, their polite suggestion that we use the pipe on all the header tests. Given the design of the pipe (essentially a long test pipe or straightpipe) and the fact that the tests were conducted pragmatically and without bias, we wondered if it might be possible that the header wouldn't make as much power if attached to a complete exhaust system. When we brought all of this information and the dyno charts to our peers and a few industry tuners, however, they all had different opinions...
you are looking at around 1k over here i believe...Quote:

but for the track thats awsome power to have a out of a N/A 1.6
i havent being able to find any test figures for the edelbrock header, any 1 found anything to prove their claim if 9 kw gain???
9 kw gain??? holy cowQuote:

cops probebly wouldn't know what it is, let alone think that the cat is taken out.
ahh the NZ boy's will remember the good Old DAys of no cat....
I got some hitechs (just press bent and mild steel though) for 220. No idea what the power gain (or loss) was but it gives a nice sounding crackle in the note between 2 and a half and 3 and a half and the vtec band sounds sweeter as well.
hitech is different to hytech.
and no way would hytech header sell for 220. they cost 1k+
you can get normal street use one.Quote:

midle = hytech
no headers has a reasonable price...hahaha...all are expensive...hahaha
its HEADER not HEADERS
lol You tell em z3lda :pQuote:

i have no vtec, i want 1 that makes good hp from 4Krpm onward and good torque dowm low and i can only rev to 7K
why dont you just get some second hand Type R extractors, there reasonably cheap, and work well, failing that save some more money and get the toda extractors, they have been compared to just about every other header on the market and always come out on top, there is a dyno comparison chart some where?
i have typeR header i got it for 130buks, it cost more to fit but owell.
im thinking of buying a jap b18c ive seen some for bought 6gs with the loom and ecu,
ill thrash my b18b for another couple of months and then make the change.
i was also looking at doin a k20 conv but it looks to expencive as there isnt many dc5 front cuts out there and a brand new k20 might cost more than my car!!
b18c7 looks the better value for $$.
ive looked at turboing but i get a bit worried as the motor wasnt designed for a turbo and might work well, but maybe not so well in a years time.
and with the price of fuel turbo will chew to much
hows the jdm itr 4-1 header in comparisson to the xforce?
both reponse wise and price wise?
not sure?
x-force 4-2-1 good for low end, tri-y for high end, they are pretty cheap,i use them on my teg,pretty good
edelbrock header 695 landed in perth woo hoo me buy
ceramic 4-2-1 1 peice:)
ive got the edelbrock 4-2-1 ceramic coated. Havnt been bothered to get them fited yet...
how do they look??
they look like cheap crap or they look descent???
what are the ports like???welds ect??
yeh they dont look too bad... welds are good.. nice long merges with nice decent size piping. Good bends as well... performance wise.. well i cant say as they are still sitting on the floor..
sweet im buying a set.
how much u pay for them??
x- force is best bang for your buck!
if i was to buy cheap header id get monstaperformance 4-1 header 249 + deliver they prob perform as good as xforce they look identical
i got mine off another member on the forums. 2nd hand but it excellent condition for $275
nice price!!!
what have you go on there now?
what size exhaust
where do u buy this from?Quote:

made in a different country and they do not share the same design
interested to know what sort of gains (kw) am i looking at if im to get xforce headers but keep the standard cat + cat back.
or would i be better off changing the whole exhaust system to make more use of the headers.

Anyone have toda b16b headers or Spoon 4-2-1 headers? With what gains?
i have the spoon headers..Quote:

cant give u dyno gains ..
but throttle response is greatly bettered..
I still think the JDM 4-1 are very good all round performer.
Also one of the few with clearance problems for a 4-1
Yes they are a very good header and will service most people's B-series combinations very well.Quote:

i mean the power gain ... is 4-2-1 have better low rpm torque or 4-1 have better high rpm flow ... :confused:
from what i gather 4-1 is better for top end power
while 4-2-1 better midrange
can somebody vouch for this ??
"from what i gather 4-1 is better for top end power

OK from what I've been told by ............ :pQuote:

4-2-1 good power though the rev range (nice an even)
4-1 might be lacking bottom end but better top end (but not my that much that its worth losing you bottom revs lol
Dave will know for sure??????? :thumbsup: :thumbsup:
Plus just how much driving do you do at top end power? lol
Not all engines are equal and have different needs and different header do different thing to em
The noob

I have Xforce 4-1 header on my ITR and I am very happy, nice sound (simular to WRX) and good power gain mid to top range.
It's vtec so I like the idea of going to the red line that is why I like it, and sound of vtec after 6000rpm is sick.
I when the Xforce 4-2-1 header on my SOHC VTec and I'm happy too...Quote:

Sounds nice :thumbsup:
Xforce is OZ made?
Do they make any exhaust system for Euro Accord and V6 Accord?
Thx.
It's OZ made, don't know about euro accord or V6, you shoud ask some of the traders, they should know for shure.
Anyone "upgraded" from X-Force 4-2-1's to TODA Headers?
I just spent $500 on my intake, and don't want to be a cheap ass on any parts (specially the most important one). I just want to convince my accountant that the $900 difference is worth it :)
Matt
TODA Headers will be way better mate without a doubt!!Quote:

wtf would you get mugen or spoon over toda?
I heard that spoon 4-1 are the best, plus spoon doesn't make sh*t parts, so that is my reason.
I am not being smart but we all know what SPOON an MUGEN are:)
Its hard to say but I think both toda and spoon would be better that mugenQuote:

1.$$$$
2. They made em for D's :rolleyes:
toda def dont make shit stuff.
IMO from looking at various dyno comparisons over the years their stuff is better bang for buck.
mugen is way too overpriced
if u c the toda header, u absolutely love it, they r toooooooooooo nice
dee ~~ get him some of ur toda header picture
i m still planning to get a really good header for my ek4, maxim works or toda????????????? :confused:
I am not saying that toda is shit (that would be very crazy thing to say) I am just saying if $$$$ were not problem for me I would go with spoon or mugen over toda, that's all, I know how toda headers look, thay are nice and they do great job but same is with spoon.
TODA all the way.
i got mugen ones atm, only got them cause i got a good deal.
but ill be goin TODA later on this year once some real work goes into my motor!!!
spoon does not perform as well as toda. toda has been dyno provin time and time again to out shine the likes of spoon and mugen.
and jun i cbf taking any pictures :P
Well I think it all depends on you car set up and what you personaly like, I like my power in high rpm's, that is why I have 4-1 (Xforce) but one day when I have some spare $$$$ I will be getting spoon 4-1.
I've got JUN 4-2-1 and 2.5" exhaust all the way... The power difference is clearly noticeable from stock exhaust. To notice it it's probably 10% better? Throttle response is better and it's faster to wind up too. The car came with these extractors, so I don't know if I would have got JUN if I had a choice, but I don't feel any inclination to change.
i have xforce header . custom mod to collector from 2 inch to 2.5 inch , and 2.5 inch all the way back with hi flow cat .. pulls harder in mid to top range .... bottom feels smoother (not as jerky and hesitant) im not sure if it has lost or made power down low tho, but throttle response seems a bit better .
its always hard to tell with NA lolz
one thing is , i got a huge buzzing sound now , kinda like a rotary engine or something (obviously not as hardcore , but to give u an idea).....really tinny and metallic. any of you get this after header install ?
any1 know how gain you get by installing x-force header into d-series?
Short answer :pQuote:

x-force would be the best and easiest to find in the west. you could sourse out other types of headers but would be difficult. otherwise places over here just customise to suit your engine. im going x-force for my d-series. have heard good things from many others. thats my 2c :honda:Quote:
