WG -
Check with the MVA headquarters up in Glen Burnie(SP?) before you go getting your exhaust changed out. If it still works the way it used to, those are the folks you have to get reinspected by, so they are required to know the appropriate laws and have the authority to cancel your ticket.
I had a similar incident occur to me in the great state of Merryland a few years back. I was pulled over and given a ticket for having tint that was too dark on the rear window of a pickup. WTF? It was behind the driver, and I had both mirrors. I knew the law, the cop didn't. Guilty until proven innocent. I had to take a half day off work and drive up to GB just to confirm that I was in the right and have the ticket cancelled.
Unfortunately I am not sure what the law is in MD regarding loud exhaust. Have you tried checking with a shop that does aftermarket exhausts? Those guys should know the laws.
