On my recent visit to the MOT station i had the chance to talk to the owner while my my car was being inspected.
I took the opportunity to enquire about aftermarket sports CAT downpipes and their ability to pass an MOT. To my surprise, the chap then said that they will pass the first MOT no problem, maybe the second if you're lucky but then they will fail! This, i wasn't expecting at all. So my question is to any MOT testers out there or any stage two or three owners, is this the case?
I look forward to your replies...
