Is a louder exhaust a better exhaust?
Not necessarily. While it is true that such an exhaust implies that there are no restrictions, there are sound considerations as well. A lot of vehicles sound, frankly, stupid with a loud exhaust. The general effect these vehicles have to bystanders is that they sound like they have a lawn-mower engine on steroids. Of course, there are local laws that concern themselves with exhaust noise, and the owner of a car with a very loud exhaust may end up getting a “fix-it” ticket, or pay a fine. Since loud exhaust is also a favorite of people more likely to speed, the local police will be more likely to give a speeding ticket to the owner of a loud car than the owner of a car with a quiet exhaust.
