Would you de cat'n your cat fail the mot? emissions

Yes it would normally.

Yea it will probably fail il just replace a standard on for the mot

Depends, there's two parts to it really. You'll pass the emissions if your emissions are low enough, which is quite possible with a well tuned engine with no cat. A car that originally had a catalytic converter will fail if it's presented to an MOT without one (i.e. a decat), but then if you have a knocked-out cat, there is no way of telling of the internal condition of the cat; the MOT tester cannot take anything apart in the test to check such things.  There are some decats out there that are the shape of cats but are actually straight throughs for this exact reason.
