Hello all I have an 88 Gxl with a K&N style intake, and a sebring exhaust on 3" piping. I bought the car like that for 900$ and it runs awesome. My question is, would the car benefit in terms of power if i change the mufflers to something else? What other best bang for buck upgrade is available for these cars. By the way my car is N/A. Thanks in advance ---------Ren

 

Port, Intake , Exhaust and Ignition i would have to say..you should try doing a search im sure there are alot of threads dedicated to this subject.

 

If you have full 3" piping you could be losing power in an NA. Do you still have a cat? If not, how are your aux. ports being opened?

 

I just got a large cat installed (wouldnt pass smog) I think the piping is 2 3/4 piping maybe 3". I have sebring mufflers. would different mufflers be better?
