Catalytic Converters for NA imports - are they needed?!

Our MK 1 imports all have de cats fitted, one because it opens the door on wasted power thats being choked and two because if its not there ,then there is no temptation for the opportunist cat thief’s to nick it , never had any issues with MOT’s once the MOT’er as been educated that they need to be tested as a import “NOT” an Mx-5.
Our MK 2’s have them also to stop the light fingered thief’s , but we fit the OE cats two weeks before MOT and then swap them back out .
