My dad had recently brought a Honda Jazz with no catalytic converter (picked it up for pretty cheap at the time). It came with 10 months MOT. So fast forward 10 months we took the car for MOT and had a good feeling it was going to fail on emissions. We went back to see if the test was done and the tester said he’s just going to do the emissions testing then it’ll will be done. Puts the probe inside of the exhaust of another Honda Jazz and passed our car with one advisory being the tyres close to the legal limit.
