So it's not really that draconian. The guy got a summons to appear. There is no fine or guilt associated with that. It's probable cause.

He ignored the first warning and got a second notice warning him he'd better not ignore it again.

Bring your car and get it tested in real controlled conditions to see if you're over the limit or not. If so you can fix it (which probably means ditching the mufflers).

Yeah, it's a PITA, but it's at least scientific instead of having some untrained cop issue a summons without any training or instrumented proof.
