i read on mazdatrix.com that the best gain in power from an exaust was from a dual system consisting of 2 pipes all the way from engine to rear bumper..i like the apex n1 dual catback but what about a header? there are no headers out there with dual outlet. do i even need a dual outlet header? will a racing beat header bolt on to an n1 "dual" exaust?. i want the best hp increase possible on my n/a that i can get from a "full" exaust set up...thanx

 

actually - there is a dual outlet header which Racing Beat makes. Mazdatrix supplies it, but you can get it at racingbeat.com

 

i would believe it's this one

all i need is that "one" header in that picture, its not 2 seperate pieces?

 

Exhaust manifold, not manifolds. Yes, you only need 1 piece then it splits at the end. If you'd taken a look under your car you wouldn't have to ask any of this

 

i bet u feel so proud typing that.
