So I will be getting my header installed within the next couple of weeks, and I was thinking about running a modded race pipe with it. Modded as in added hi-flow cat. I wanna keep as much low end tq (went with TE header) as possible without going back to the ultra restrictive factory pipe. I was thinkin adding a cat to the racepipe may do the trick. I know TE sells one as such, just wondering how much, if any, of a difference it would make. TIA, rep for useful answers.

good luck with that one. And we already went on about the backpressure myth, which, it is a myth. Use the search feature

high flow cat = no gains i had one on my maxima made no difference maybe 1 hp if any. dont bother. though an aftermarket one usually is a few pounds lighter, but not by much, if your goign for wieght saving them look else where first before this

mine was a random paying $200+ plus for it

did you actually dyno your car? bc I had an 01 maxima with a random tech cat and they "said" it was dyno proven for hp gains...I never got mine dynoed though. Also the random tech high flow cat for the acura tsx supposedly gives about a 8 hp gain to the wheels
