Slap a cheap standard exhaust on, maybe borrow a mates? Unless the exhaust says "not for road use" it is at the testers discretion. Mine passed with a pm52 pipe which i know isnt road legal. He just put an advisory on it saying exhaust noisy. This is a legitimate garage too.
Yeah every mot i have had all the exhausts have been de-restricted and never been failed. I have this TDR tyga exhaust, probably one of the loudest exhausts ever for a ped! well mine is.. and it passed. and its not even road legal
The bike u got off me with the TDR pipe doesnt even need MOT lol...? so how do u know if its passed..
