I wasnt happy with Hotbodies undertail's sound or performance. So I used their midpipe and battery box and fabricated my own system. I used a yosh pipe and hanger, heat wrapped everything, and custom laser cut a heat sheild out of stainless steel with my companies logo in it. I chopped up their undertail to keep rocks and mud from underneath my tail. buried the brake and tail lights in the opening. Then I decided to mount the NOS bottle some place new instead of the all the usually spots. Then when Im not feeling froggy I decided to buy a QB carbon solo cap, love the bodylines with it on. the sound is soooo much better with the yosh. Let me know what ya think of mods good or bad I can handle it, AND LAY OFF THE SWINGARM and TIRE. I know no more corning. later Brian
