The biggest problem I had was with the angle adapter for the upsweep. The thing just wouldn't quite fit over the exhaust pipe. I tried one of those pipe expanders that harbor Freight sells, but it didn't quite cut it either. I ended up going after the pipe with a blest sander and took off the stock exhaust hook in the process. That cured the problem. There's plenty of meat on the end of the pipe, it's about 1/8" thick. If you leave it in the stock position, you're done, although I think I had to cut and redrill the mounting bar off to get it to reach the rear footpeg mount properly. I needed to move mine inboard and down as much as I could to clear the rearset brake pedal. The rearset story is a tale in itself,
