Also, I think I've read somewhere that a new Cat needs to be run for several miles before it becomes fully activated?
Does anyone know if that's true?
I'm sure I read that someone's car failed on a faulty Cat, bought a new one and went back to the MOT Station and it failed straight away as it hadn't become active yet?
What's the score with this?
Cheers
