You will need to replace the de cat with a cat and then run your car for a couple of hundred miles before taking it in for it's MOT to give the system time to realise that it has a Cat fiited and pass the emmisions test


PS It's a straight swap by the way

You would be much better off getting a sports cat mate, your insurance is probably void when having a decat fitted. If you have an accident, your in the brown smelly stuff....
