I have a supertrapp E.A.R. exhaust on my 620 that is near new condition (or at least looks great). I would like to trade anyone for the original exahust.. I am having a hard time getting below 96 db with the supertrapp even after repacking it. I hope the stock is much quieter, I know I will be giving up some HP and probably need to rejet but this is not my race bike.
