My brother is getting a 2007 Grand Prix GXP V8. Any thoughts on mods? We are gonna get him a CAI, exhaust, and tune. Just wondering if any of u guys worked on these, or have one, or know a friend with one. I want to know what brads I should go with. I was just thinking K&N CAI, and either a Flowmater or magnaflow exhaust. I dont know on the tuner. Any thoughts? Please let me know thanks guys! :beer:
