I've come to the decision of just paying off the ticket but not actually "fixing" my exhaust system. I'd honestly be miserable if I had to say goodbye to the sound of my muffler. So I'll just pay off as many exhaust tickets as I have to. I've actually driven by lots of cops since I had my exhaust system installed. Been in front of them, behind, passing them in the fast lane, etc. I just happened to get snagged by one of the assholes. It'll probably happen again and again, but I'll just have to deal with it, because I don't want to quiet my muffler.

Thanks guys for all the help.
