Had both Cats removed from my exhaust and the MOT is due shortly,passed the last one with only the back cat removed.
Do you think it would pass with just the back cat on or would i have to put the front cat back on?
Would rather just put the back cat on as its easy to do but dont think that will be enough to pass?

If the car is tested wit a hot cat, it should get through with only 1, though left awhile to cool down - slim chance
