Installation took 10 minutes. This is what I did. Removed the bracket nut & bolt, remove header pipe clamp, remove retainer spring on front side of header pipe, slide old muffler off gently, remove asbestos sealer collar on header pipe, install new header pipe collar, carefully slide hindle exhaust over head pipe being careful not to damage the much thinner new sealing collar, attach bracket mount bolt & spacers, use red loctite on mounting bracket nut, make sure new pipe is fully on the head pipe. Hook retainer spring onto head pipe, using vise grips extend spring to hook into retainer spring eye on hindle pipe. Be careful not to injure yourself. Make sure everything is aligned properly before tightening pipe clamp. Mount pipe clamp so that it does not protrude below the lowest level of the head pipe. Tighten securely according instructions that came with hindle pipe. Start motor and check for exhaust leaks around new pipe seal. If any, re-tighten until gone. Let idle 10-15 minutes to "burn in" new muffler pipe. Let cool, start motor again run 5-10- minutes checking for exhaust leaks again. Now ride- it sounds GOOD ! Spyder running 2+ bars cooler.
You can do this !
