Looking to do major mods on '04 GP GTP

[whiz92]

Hi I'm a proud owner of a 2004 Grand Prix GTP with the Comp. G package and I'm ready to start upgrading and tuning it. Money isn't an issue so right now I'm looking to do a 3" Stainless Catback exhaust from ZZP, XPZ cam also from ZZP, build a custom CAI pulling from the wheel well, and do some head work. I need help with selecting supporting mods so that I don't end up the idiot on the side of the road with $8,000 of junk. Any help or suggestions to a different cam, exhaust, etc. would be greatly appreciate

Well their cams are from Competition Cams which is a industry leader. I think the 3" system is overkill and may actually hurt performance and the 2 1/2" is a better choice.

With the level of mods you want to do, you need to look into a custom tune to get the most of it. Dyno tuning would be the best bet. Or someone that will drive it while they tune.
