exhaust performance question ??
 

Hey everybody I am new to this site and just got my first car which is a 92 civic si hatch.

The car is all stock and i wanted to put an intake and exhuast. are those cf intakes any good??

I wanted to put a full exhaust and wanted to know how i can gain power
headers, piping size, stock or hi flow cat??

Thanks

Most intakes are good, the cooler the air induction the better. k&n type intake filters are good, good flow is important. Exhaust 2 1/2" pipe is good. full flow cats are the best. (except in Ca. every 2yrs smog ck due, original cat needs to be put back with sensors) need to ck with the state your in on full flow cat. and Mufflers. Turbo type muffler is good, mild but not noisey, not much back pressure at all.
