It's pretty loud, it gets looks everywhere, definitely an eye catcher, but no cops hassling me so I take it I'm ok. I stuffed it with steel wool because of the oil that spits out. It runs like a champ though. The actual reason I even chopped it down like the was because i tried to run it without the baffle and the sleeve came off and a car right behind me ran it over so I had to do something quick. ha.
