Hi guys,

I have a S2000 2.2 with a Hondata Kpro
Invidia 70 mm test pipe
stock exhaust

I actually have 216 whp, and my setup is fully tuned on dyno



I made some search about header, since my exhaust don't make me loose a lot of whp (I tested open test pipe and I have only 2whp more)

I take a look at ASM, Amuse, Toda, T1R, Buddy Club Race, and ASR


the ASR is the only one with 4-1, it has a megaphone too.

Does some people here have good or bad experience with those header, with dyno sheet?

 

J's ?

 

T1r or J's is my vote.

 

Toda or J's...

here's the definitive thread on headers from the NA forum:

According to a test of over 10 brands done by Super Autobacs, the Tracy header is the one to buy. I found the article somewhere... It had dyno graphs of tons of them... I think I got it from Bulletproof, so maybe shoot them a PM.
