Great exhaust and perfect fit. The bolts for the cat and the end of the headstock were too short. I had to replace. There were no screws for the O2 sensor in the kit. The ball joint has no seals and springs to hold tension, but it does require some fiddling to keep it from leaking. otherwise it's been great so far. removed his cat and went straight to the flowmaster 40 series muffler and it sounds great
