I just bought an 03 GT I want to add headders and an H-pipe. I 've done some reading but it's very contradictory. A lot of articles say MAC is good, and others say BBK are good. Has anyone out there put headers on an 03 GT, if so let me know how you did it and how you kie your pipes! I want to make sure before I invest my money into making my GT loud!
