Police have arrested my motorbike!

A few month ago, when I was riding a motorcycle, police suddenly stop my motorbike, what's my mistake? it turns out the cause is my racing exhaust on my motorbike. Oh no.. Guys, actually, my racing exhaust is not too noisy, the sound produced from my racing exhaust is still relatively quiet, not so noisy, but maybe I'm unlucky, the police have arrested my motorbike .. an unlucky day for me.(Pic:
