Fortunately I already had the Superior mufflers, taken off my pan, knocking around the garage. The upsweeps came from Paughco. I like theirs 'cos the rear pipe comes up in one continuous sweep rather than a straight part then the upsweep.
Here is the reason I had to swap them out. This was the front pipe that came with the bike. It has a notch to clear the frame. The front head overheated big time.
