which is better, and are there any fitman issues anything that need to be modded to fit on a 97 gxe non-cali, and which is better....

jdm71488

no issues... there is a write up / review on the CM one... just go to vqpower.com, i think it was... gtr_rider i believe, dont want to check... you can search.

the headers arent really worth it... the only ones that are is the cattman headers, but they have only been proven to give a few more horses, not anything on the track. unless you are FI... thats a different story!

btw this is all hear say... but i try not to talk out my butt...

I agree with jdm71488, headers really wont give you much gains, especially versus a y-pipe.

I wonder how benificial it is for FI?

wait dont FI cars get their own set of new headers? (turbo specifically)

gold4thgen

are the ebay headers any good, their like 260 buy it now ith the y pipe it sounds like a good deal but are they worth it, i dont care about quality that much, dont plan to keep car forever but are they worth it or should i pass and go for a cm y pipe???

are you talking about those stone racing???

well if you want to see the dynos click here

18 WHP
14 TORQUE

thas pretty good gain... im buying the y-pipe from them pretty cheap.

turbocharged has to run a turbo exhaust manifold because a TC is run off exhaust gases... but a supercharger is driven by belts so your headers wont be affected...

That dyno is a comparison of OEM to aftermarket.
To see a true beneficial gain, they need to do a dyno comparison of their headers and another Co.'s aftermarket y to see the true gains over a y pipe.

New headers are not required for a turbo'ed max. Only on cars that the turbo bolts directly to the manifold is it required. On turbo'ed maxes a collector runs the exhaust up front in a reverse y type thing. This piece bolts right onto the stock headers.

get a budget y pipe. cheap and also great quality. i stand by my budget and it has been in for nearly a year now with no rust/sound or leak issues.

Headers give you a "cool sound" and maybe 2-3 hp over most y pipes for the VQ30. The VQ35 gets much better gains supposedly. A y pipe alone will give you 18hp. http://www.motorvate.ca/mvp.php/504 It is really up to you if you want to speed the extra money and the PITA install.

Yeah most people don't run headers with either SC or turbo. A 3" full exhaust with stock manifolds (~30whp over most of rpm band)(coudn't find post that had working dyno graph) is better than cattman headers (~20 whp in a very small band). Cattmans are the only ones that look to be good quality and anywhere close to being worth the money and effort. A good 3" high volume headers for forced induction would give you good gains. Besides that I wouldn't bother with it.

There should be a FAQ or sticky about this already.
