Which exhaust is on your bike now? If it is not using the servo now you'll need to check and make sure you still have the cable that connects from your servo motor to the muffler if you put a stock exhaust back on.
I was wondering do they fit as far as attachment and header alignment and it sounds like they do. If the kickstand interfers a little I can grind that notch, thanks for the heads up. I think I read that the Ulysses muffler has thicker metal on the bottom or some sort of internal reinforcment added for bash resistance? I saw a Uly where the guy welded a strip of plate along the bottom to prevent dents when sliding over rocks etc. It looked hell strong!
