Hypothetical question for you if you don't mind.
If I had a year 2000 car that requires a CAT test and fitted a year 2000 motorbike engine on carbs that never had a CAT from the factory how would the emissions be tested?
Cheers

This I'm unsure of. CAT's are not required for an MOT though, it's only the effect they have on the emissions that's tested. You can therefore in theory remove a CAT from a 2010 car and if you can get the emissions down to the same level as with the CAT it will pass. It'll probably run like a bag of balls though.
As a rule of thumb for emissions at MOT the test is on the gae of the car or engine, which ever is the
older. So new engine in old skool car is fine. Old skool engine in new car needs to meet the emissions of the car not the engine.
