Overall kit fit pretty good after we straightened the pipe tips to connect to the other pipe. The exhaust pipe should fit over the muffler exit not inside of it. A gasket would have been nice in the kit. Drop everything, drive to parts store and find a gasket. Other then that, it looks and sounds pretty good.
