after the thread regaurding if cats were or werent legal there seemed to be confusion as to wether a car without a cat will pass an MOT or not. some argued that it will pass providing it doesnt fail an emissions test and others that the car had to have a cat fitted to pass regardless of the emissions. can anyone give me a definative answer to this and possably a link to something that states that the car either does or does not need a cat to pass the MOT ? cheers
