The interior sound level isn't bad. It doesn't start to really resonate until about 2500 RPM, and with the gearing I've got, at 80 MPH I'm only doing about 1800-1900 RPM, so it's actually relatively quiet. Get into it though, and it does get loud inside.
Sounds pretty good man. And that's a lot coming from me, because I'm definitely not a loudmouth fan.
