Goes of age of car not age of engine pre cat equals no cat test, tell em to read the vosa rules, if there is no data for a 3litre mr2 v6 in the system they go of age of car ffs.

I will text my mates to get clarification I know after talking in the pub to George my mot tester I don't have to have a cat test even though my car engine would probably ace what the old 4age chucked out.
