Wow can't believe some of you. Lol go to court for what? Because a cop gave you an EPA? I guarantee most of your exhausts are over 90db as is mine. If a cop sees a cannon on the back of your car he will assume your car is loud but tell me is he right? My guess is yes.
Unfortunately it's on you to prove your car is legal and it is unfortunate that we also have to pay for it. But why whinge about something that you know is illegal when you put it on the car. Simple thing. Either stop complaining about it and take it on the chin or do what Emsta did and buy a quiet little girls car so you can be left alone
