My car has just passed with only a centre cat in place, 1.003 lambda, 38 hydrocarbon and 0.01 CO, it will pass no probs but cat needs to be hot and your lambda sensor needs to be spot on..

I remember when I took my other scoobs (my97) and only had a front cat n that passed with no probs at all. Ive mentioned before bout my old scoobs, it had done 197,000mls aswell, loved it but needed to get rid as the milage thing was starting to worry me...
