Are loud auto/truck mufflers cramping your style?

It’s no wonder I have to wear hearing aids. Since the 1950’s, factory installed auto mufflers have gotten louder. Not to mention loud motorcycles with the baffles taken out. And, not to mention auto mufflers that are not stock from the factory. One driver asked me one day on a traffic stop, ” what gives you the right to determine what’s too loud on my automobile”? After issuing him a citation, I explained that i could hear him coming towards me, at least a mile a way. He had no mufflers, just straight exhaust pipes. He paid his fine. Question: Where you live, do the police actively enforce the loud muffler laws or is it just overlooked?
