Actually in WI it is illegal to put on ANY aftermarket exhaust that exceeds the stock decibel level. Most state troopers know that. I had a similar situation happen to me, but when I said something he pulled it up to show me. So, you can try to fight it, but you'll probably end up losing. Just put the stock back on and change it back after you have it passed.
