decat + MOT

[Razorback_Rob]

A mid box looks completely different to a cat though....might fool an old lady with that, but an MOT tester that's under cars all day, every day!?


Just in case it's been missed, presence of a cat/DPF (where originally fitted) is now checked on the MOT for diesels.

You'll pass smoke test without, but depending where you go, it's unlikely they'll pass a straight pipe. Be better to gut a cat and refit now tbh.

Or do as I and a few others are doing. Get your old cat and cut the shell off. Then weld around your straight pipe to appear as a dummy cat
