Ok, I've got an 03 GT with 6k miles on it. So far, all I have done is just the Magnaflow exhaust, and I put in a K&N filter. Basically, I want to do alot of bolt-ons the next couple of years, until my warranty runs out, and I can supercharge the car. What mods can I do, that I won't have to change when it comes time to supercharge the car? I don't want to spend money on a mod, to have to change it again later. Also, what are the different types of superchargers to look into? I don't have a clue as to what type to get. Any help?
