Thread: Computer Upgrade!!!

pretty much all the motor mods for the 97-03gtp will work for the 04+

and you dont really need the whole cat back exhaust. all it does is change the sound and you can do that with mufflers. it gives you no performance. if you want performance get headers or a ported manifold and a down pipe.

I put down 192whp in my BONE stock 97 GTP...then I did the exhaust and intake and put down 214whp.... it does make a difference...
