I don't know how it is where you live, but in South Bend, Indiana................they need to worry much more about the damn car stereos, then the exhausts. I could never hear their exhaust if it were missing both mufflers with the damn stereos around here. Maybe they should enact a law that prevents buying a stereo over 50 watts. (not to dis you stereo guys, but turn the damn things down in residential areas).
And Harleys.....................well, I guess they are gonna have to just ban them all together.
