My local independent were telling me about a cruiser type thing that had straight though pipes (looked like steel drain pipes) in for an MOT.
It was so loud they couldn't start it in the workshop because it hurt their ears too much.
Failed it and insisted on baffles being installed. Still bloody loud.
They were saying they let loud exhausts through, generally, especially if it was removable baffles, as they can just be popped in and out.
Like previously mentioned, if it was a faulty exhaust they would fail it.
