Need header help

[Crushed_Skull]

Im upgrading my exhaust for my new B18B in a 94 Integra LS to 2.5" and need some advice choosing header. Does header have to have to have 2.5" outlet or would normal choke it a bit. Im looking to spend about mid or a little higher. Thanks.

get whatever header you want, it won't matter if you still have a cat on the car. as far as I am concerned, DC sports makes great mid grade headers, and they are C.A.R.B. approved for the smog states!

get a kamikaze hedder, they out performed the dc hedder by 5 hp on a dyno, plus they have a really good size down pipe. they flow really nice, i have kamikaze and they feel really good at mid to top end.
