Gt Mods

I have a 2000 Grand Prix GT. I have an intake and INTENSE PCM in it right now. I was wondering what mods i should get next and im on a very small budget. THANKS.

I've learned quite a bit just from reading about other posters upgrades to their cars. Intake is my first planned mod, then exhaust.

I've heard some GT aftermarket exhaust systems that makes me want to string the audio clips into a lullaby that I can listen to before bed :D
