i'm looking into buying some headers for my 01 GT my current mods is only a magnaflow catback. I plan on putting in an accufab 75mm throttle body and plenum, headers a catted x or h pipe, a k&n fipk, and also getting a diablo programer to get the most from my set up. But anyways which headers give you the best gains long tubes, shorties, mac, BBK, or how about the Bassani mid length headers i havent heard too much about those.
