I've got a 2006 4-door G6 GTP and I'm looking to maximize the performance as much as possible. As this car is so new, I don't yet see a lot of bolt-on performance parts at my local auto parts store. What I'm looking for are exhaust system components, intake improvements, chip sets, whatever performance parts are allowed that won't whack my warranty.
I used to live in California, and now I live in Georgia so I believe I can scrap most of the emissions worries. What do we have out here that I can bolt on, or have my dealer install to kick this thing up a few notches?
