This past sunday, I used the lift over at my dads house to put some 4'' exhaust resignator tips on my 00' stang. The stock ones look nice, but they don't fill out the cut-outs on the bumper like they should. I have a set of borla stinger mufflers I almost put on, but I don't have a welder, and I didn't feel like putting clamps on that. Once it was all said and done, it looks awsome, and I can tell a tad bit denser sound, but not by much. I am pleased with the look and I wish I had a camera to take pics of it.
