The issue is with the police, not the MoT. They use the information on the registration document to determine dba level for a given vehicle 'type approval', for the 961 it's shown as 90dba@3750rpm. The police also have the authority to inspect the silencers for compliance markings, unfortunately the Norton 'shorts' are engraved 'not for road use' which is a dead giveaway. The MoT don't check dba levels so noise is down to the examiners judgement and a fail because of noise is cheap in comparison to the fines that the police can dish out.
