ok, i have a 65 stang, and i kno just about everything i can do to that to make it fast, but i just bought a 2002 GT. now i kno these cars a quite a bit different than the classics, and i need to kno what i can do that is relativly cheap that will give it more power. right now it has 2 cats removed, 2 flowmasters, and a K&N filter. i was planning on adding an X pipe, but dont kno which one would be best. so any input would be greatly appreciated.
