OK ,my two cents on this, in my area of Nc. the little cars are the noise makers that are the worst , I live within a mile of a large Road here in town and it doesn't matter the time of year you always here the little ricer cars ,yes I do hear some bikes too ,but not as many ! I know some bikes are just way to loud and they should be held accountable but it shouldn't be Barny fifes job to decide this matter.We have yearly inspection for that here. I just think that most govt. should worry more about the people who are watching TV. while they are on the phone to whoever is more important than driving ,with their coffee in the other hand so they cant use there turn signals to switch over three lanes in rush hour traffic is more important than if a muffler is a little loud and they cant hear their phone call !
So I'm not going to argue that loud pipes get attention ,because they do or people wouldn't want to ban them! Notice I didn't say saves lives !
