I looked in the self help section but I did not see anything on changing exhaust. I want to change out my short shots for long shots. I had them done at my Harley dealer before, but I would like to do it myself this time to save a few bucks. Is it very difficult or should I just let Harley do it?? Any step by step tips I should take?..I figure I can do it for around $450 vs $600+ at the dealer.
