I got pulled over by tyson's for my car's exhaust. The lady officer pulled me out of the car and was telling me that it was illegal. She saw that it was my birthday that day, and said she would be nice and give me a warning ticket because I was polite and it was my birthday. She said most cops won't write tickets unless the driver is a dick about everything, in which case I guess they do deserve one. If you really wanted to push this forward, not sure if its worth $85, but you can take the claim that its 50 state legal claim to court. If the court decides that you're still at fault, contact the manufacturer of the exhaust and tell them to reimburse you for false advertisement, which if they don't then you can sue them. On the other hand, you can just pay the fine and just move on. Post how it went, pz
