A 4-2-1 header does not make less power than stock. However neither of you can say anything factual about the matter since neither of you have any sort of dyno results that you're quoting from.

I have had trouble with my DC Sports header..
But this is mainly because my engine (B18C1) is placed in a British built car..
On my stock header (EPDM ITR) the O2 plug is installed on the collector of the header.. On my Header fron DC there is no place for the O2 plug..
Apperantly (after telephone talk with DC) they have hade the same problem in Canada? I was told that the O2 sensor is placed in the cat. on U.S GS-R´s??
Anyway I have to cut my exhaust and build a small adaptor to get it to fit..

I am running the JDM type R 4-1 with 2.5 carsound and 2.5 all the way back with an es oval muffler (shortly) right now a fart can, but the car really opened up in the upper RPMs with the addition of this header and exhaust system..
