what size exhaust do we have and what size should it be? i was thinking of getting the pacesetter header (polished one), with custom pipe and a magnaflow 1-2 muffler because i think our cars look wierd without 2 tips. Also, is there a resonator i should use etc? My friend took his off and he actually got slower when he added his header due to no back pressure until he added a resonator.

I have a pacesetter 4-1 header , purple hornies resonator with a catco highflow cat with 2 1/4 piping all the way back to a borla muffler.

I beleive we have 1 1/8 piping ( i think thats what the exhuast shop said, dont quote me though ).

Sounds very deep and gave me a much needed gain in HP. Good luck ...

1 7/8" inside diameter pipe stock.

thanks
