I am thinking about swapping out exhausts. I love the sound of my Flowmaster dual in/out, but miss the hp and tq I lost. I did get a little hp on top end but thats not really where I want it. Any thoughts on the Gibson cat back exhaust system would be appreciated. By the way I'm talking about the one shown in the November issue of Sport Truck. It is a 3 inch system. Y-pipe to single in single out exhaust.
