    Those are stock GT-A mufflers. Stock on the Shelby GT, same as the Bullitt exhaust, GT-B’s, with different tips. These have the FRPP 4” tips, same muffler housing. Similar to the Borla s Type I think. In between stock and the louder KR’s.

    The Ford Racing GTA's were indeed stock on the Shelby GT. However, they are not the same as the Bullitt GTB's with different tips. The GTB's are still in production through Ford Performance Parts as part # M-5230-GTB. The GTA's were manufactured for Ford Racing by Supreme Performance which went out of business in 2009-2010. Also, the muffler housings are completely different compared to the Borla S Type mufflers which have round shaped housings. The GTA's had oval shaped housings. The GTB's share the same resonated tips as the FR500 KR mufflers but have oval shaped housings just as the Supreme Performance GTA mufflers used to have.

    Thanks for the info guys, I figured for $50 it was worth picking all this stuff up. I’ll throw the mufflers on and see how they sound, my MACs are great but the neighbors aren’t such big fans!

    Also, another question, anybody running these catless with long tubes?
