i had an old school SuperTrapp, the megaphone shaped one. Had it on a 250xr for maybe 8 years and only repacked one time after about the first year, when I was still anal about keeping the bike in near new condition. Never packed it again after that and it never seemed to get much louder the new.
But that was on a 250, don't know about a 650?
