On a different slant regarding MOT's. what excacly is the position regarding removing a Cat after passing the test. There must be loads of us putting it on once a years then taking it off, I have yet to see mr plod test a car but I believe some do carry test kits.
What would the offence be ?, is it a fixed penalty ?
Obviously you can't claim it passed the MOT, or if you do your going to cause big problems for the MOT station. As I am quite freindly with my local MOT station I would not do this to them.

ANY THOUGHTS ?
