I'm not an MOT tester, If your car left the factory with a cat then yes it should have one present (A complete exhaust sytem) to pass the MOT test.

I knocked the guts out of my cat and refitted the empty unit so it looked standard when I had my DTI. The dervs only have a smoke test but the exsaust sytem must be intact with no bits missing.

cat/dpf removed passed MOT fine, section 7.1 (i believe applies) If car is eligable for a full emissions test then it must have a cat or something similar..
