Very nice exhaust system, crappy clamps
By Russ
First, this kit is designed for a crew cab truck and I put it on a 2005 GMC 2500HD extended cab. The kit fit just had to do a little figuring on my own on where to cut the existing system. The quality of the system is superb, strong steel, perfect welds, very well designed. It looks and sounds great. I had a noticeable boost in power with this kit. I also gained +/- 1 MPG on the highway with this kit. The 4" exhaust pipe and tip look great on a heavy duty truck.My only complaint with this system is the exhaust clamps that come with this system. I can understand the front two leaking because of the strange angle of the pipes, since I did put a crew cab kit on an extended cab. Even the big 4" clamp that attaches the pipe to the rear of the muffler leaked. They weren't just small leaks either, very loud and very noticeable. Played with them and re-tightened them over and over, no success. It wasn't the end of the world, I got the system set up how I wanted it and welded all the pipes, for a professional installation it should all really be welded anyway.
