I took my TBA in for the 500 mile service today however the owner with the SuperTrapp exhaust cancelled but indicated that next week would be good. The dealer said that the exhaust is a custom system they put together. They also are replacing the right pipe which has turned blue and adding chrome rear peg supports and sprocket cover. BTW, I had a fun 120 mile mountain ride before taking it in and the TBA is so silent, I could hear the Harleys before I could see them around the curves.
