While it's different sounding it's not loud and obnoxious, it was a bit of a fight to get it to mount where I wanted. It looks good on the bike since they're blue and the exhaust matches my bikes I have 2 of them got one going up to 42 mph that's a 50cc moped doing 40. 35 is a good cruising speed around here.
