And that's fair. Loud pipes do have a potential for abuse. I take a lot of care rolling into the neighborhood to not blip the throttle.
Unfortunately, too many guys don't take that care. The guy across the street has a rather loud Wide Boy, and when he or his buddies pull away from his place they without fail do so at full throttle making as much noise as possible. And everyone within earshot (that I can see) flashes them a dirty look.
