I have been back and forth with several reps in my area. I have beaten 2 exhaust tickets in 2 years. Some of the facts that I have found is there is not a specific noise level to classify what loud or noise is. In addition there would be a major flaw in the bill with performance model cars such as m3's, sti's, evo's, Srt series cars, etc....
