I just got my 2002 GT and I already have plans for a cat-back (Magnaflow) exhaust to go on. Removed the air silencer and nothing more. It is my first 4.6 parked in my garage (previously owned a 96 V6) and I am not sure where to begin to modify the car. I would like to stay away from anything too expensive (supercharger, nitrous, etc.) as I am still in college and don't have a large bank account yet. Basically, I am looking for the best bang for my buck and any advice would be much appreciated.
