I thought it sounded quiet at first but it seems the more I ride it the louder it gets. I guess it just needs to be broken in, who knows:dontknow: My buddy was driving his car and I passed him up so he could hear how it sounded and he said it sounded bad ass. Im happy for now until I can fork out the cash for a full system.Yeah, it sounds great for the $$$. Dig the pops. When I threw the Akra link pipe onto it it was poppin' like crazy and exhaust note turned to poop. Def sounded like it needed a tune with that. But on it's own, just the growler sounds killer. If anything, a hair too quiet.
