Yesterday, I was coming home from school and I noticed a cop following me. I was not speeding or doing anything out of the ordinary. His lights flashed so I stopped thinking wtf is going on. He writes me up for having an "illegal exhaust."

I have a ractive MT631C

He said anything that is not stock is illegal because of a sound increase. I plan on fighting this and arguing that my header/intake caused extra airflow and it was not the exhaust's sound.

Does anyone else have any suggestions on what I should do?

Thanks
