Ok well after aggrivation putting the x-pipe together. And then many trips back and forth from the auto parts store trying to find the right belt for the stang since I also deleted the air pump. But when I finally started it..... I fell in love with the stang all over again. I installed a 2 1/2" High flow catted X-pipe which I have to say, was great quality! and pretty good fitment. Just have to make a few adjustments to the left side because the tip sticks out a bit further than the other. But no big deal, very easy to adjust. The difference it makes is incredible. I love the new found awakened power of it, and the freaking awesome sound of it. I even noticed an instant increase in MPG. And no more exhaust leak, rattling, exhaust smell in vehicle with a/c on recirc, and air sound from the pump.
