Well it's pretty obvious a cobra with an o/r x-pipe and borla stingers is loud, but not when cruising at 1700rpm. I was given an exhaust ticket for exactly that and told that anything that wasn't stock is illegal. Well how did the officer know my exhaust wasn't stock, it's a 500hp cobra of course it will be loud sometimes, especially if she didn't have a decibel meter to tell? How is this legal that I can be charged with something that an officer has no proof of other than "yea, it didn't sound stock." What is the extent of what cops are allowed to interpret; what I mean is how much water does their word hold without concrete evidence? If your going to charge me with an exhaust ticket then I want to see the evidence of you testing how many decibels my car made it to.
