Yesterday I just installed my first mod which was the JWT Popcharger and now I'm feenin' for more power. So what two combinations of test pipes and cat-back exhaust system will give me the maximum amount of horsepower? TIA

 

Any combination will give you decent gains. There isn't really one setup that will really differ in performance from others. Might be like a 15 hp gain. I'd go more for what sound you want.

 

the new APS exhaust looks really nice.

 

kinetix resonated test pipes + injen straight tip exhaust = good sound

 

As far as sound goes, I think that high flow cats put out a better sound than test pipes do, even resonated ones. But if you are trying to squeeze every last HP out of your Z, then the test pipes do put out a few more than the high flows.

 

ill be going stillen test pipes.... i already have stillen exhaust.

 

Any true dual exhaust will do some good justice.

 

a true duel will give you better power gains if your boosted

i've heard that it's better to stick w/ a y-pipe on na cars for more power... i haven't read much supporting this though

 

ummm, stupid question, where's the y-pipe located? before or after the cat's?

i'm still deciding on what exhaust set up, but i think so far i'm gonna get the rsr exhaust, sounds deep.

 

right after
