I just picked up a 98 grand prix gt and i was just wondering if anyone can help me out with how should i do a exhaust system for the best performance i can get. Also would like to know what bolt ons work great and ones i should stay away from. Thanks homies!?!?!?!?!?:cool:
 


Read and read some more.

Exhaust sucks, you gain zero power from anything after the cat converter, and 90% of aftermarket exhaust sounds terrible and drones.
 
Being a GT, you will have little to no gains from headers currenty.
Bolt ons to consider:
ZZP ER rockers
ZZP HV3

Bolt on's to stay away from
ZZP TB heat shield
ZZP TB spacer
ZZP plug wires
MSD coil packs
Bosch spark plugs
Bosch O2 sensors
 


As a former bolt-on GT owner I can tell you first would be to make an intake.Then since your a GT you can either do headers or the ideal ZZP plog and a 3in downpipe. With those 3 mods you will gain some decent power thruout the powerband just to get things going. Then the big mods will come into play like the ZZP HV3, ER rockers and a tune. Once all is said and done you will be plenty faster both off the line and from a roll. You will probably gain around 40hp or so and you could always add enhancements too such as a shift kit,poly mounts, and alt voltage booster.
