Just incredible that there isn’t a fail for a corroded exhaust. It’s also ridiculous not to be able to acertain the extent of the corrosion and the “punter” being pissed off is irrelevant. Either way they would have to fit a new exhaust whether it’s been poked with a screwdriver or not as it’s not fit for purpose. Thanks for the information. I didn’t realise how pointless the MOT test is.
