Dave, just about all of us ask the same thing when we got our cars. There have been tons of posts regarding the topics. Not being a **** but if you search you will find tons of interesting material about power gains etc. Most good topics would be Cold Air Intakes CAI's (needswings or TVT) Mufflers, Ansa or magnaflow, TVT upgrades and sprint booster- theres an upgraded one thats pretty sweet. Also topics of reducing weight etc can help.

welcome to the forum and enjoy the assistance this group constantly provides.

PM me if I can help you with anything

Pooly
