Hey everybody, new to the GP scene. Just bought my first car 1998 grand prix GTP. I have worked on plenty of other cars just no prix's so far. I have been doing some reading on what people had done to their cars and like what I am seeing.


I need input and ideas of what I should do performance wise, I am set for cosmetics but performance comes first. I have read that you need 180*C thermostat for smaller pulleys.

Here is what I think is a good list in order of what I should do so far.

1.180*C therm-easy install 10$ no biggie
2.Haven't decided either a FWI (need suggestions of which) or a ram.-another easy-med install making own is not an option haha
Here's where it gets fuzzy, not entirely sure what to do here..
3. Headers,Downpipe,hi-flow cat,new mufflers, just a big blur...

Advance thanks for all the help and input. I am open to any criticisms and help you can offer don't hold back first time working on one of these and criticism is easiest way to learn
