Header questions, JDM, Kamikaze, DC Sports? slightly different question
was curious are there enough gains to opt for a 2.5" collector header say the JDM 4-1, Kamikaze, vs. a decent brand 4-1 like the DC Sports.
I'm currently pushing 8-9psi on a JRSC running a USDM Typr-R header->2.5 Carsound->USDM Type-R exhaust. I will NOT be changing the cat or exhaust (I can modify the cat to fit a new header though). But was wondering if changing to a DC 4-1 header would provide decent gains or would going with one of the 2.5 collector headers be worth modifying the cat and a better choice?? Or would the gains be so minimal I should just leave it all alone? I'd be willing to swap in a new header to pickup 10+whp, but if I only get something like 5 whp... I might as well leave it all alone.
I'm cross posting on the Hostboard just to try to get some more feedback/input. I've been told that a header is not worth getting since I won't be changing the USDM ITR exhaust.
any input or feedback is appreciated.

Re: Header questions, JDM, Kamikaze, DC Sports? slightly different question (Black-LS)
I feel as if you arent going to free up the rest of the exhaust I wouldnt worry about it. Having run a Kami, 2.5'' Test pipe, and the N1 it was louuuuud.
However when I made the switch from the header back I picked up ~15whp but I was also running 11psi so the results yielded of course were greater.
Its all personal preference, but i dont think you would notice more then a 5whp difference give or take if you did simply the header.
If you do decide to do so I have a Mint JDM 4-1 sitting next to me waiting to be sold.
Good Luck, Joe.

5 months later and I'm still wondering... anyone else have thoughts on this?
