I'm not suggesting a ban on motorcycles. I'm a motorcyclist myself but I use the stock exhausts because they are quiet. I do want to ban excessively loud exhausts, or more simply, I want the police to enforce the existing noise pollution laws.

I think that an important part of being a decent human being living in close proximity to other human beings is recognizing and limiting one's own anti-social behavior. I hope that's not a controversial statement.
