As long as you actually have insurance and valid registration, you can get out of those tickets.
They will nail you for inspection, which is just a fine. The license thing, hmm not sure about that. Loud exhaust…If you can quiet it in some way for your court date then you can say it was fixed or whatever.
My little bro was pulled over a few months ago for no insurance & loud exhaust. He fixed the muffler and proved that he had insurance and I think all he got was a $20 fine. They told him he would need a lawyer as well, but that was not the case.
