Hi all,
Aren't CAT's now only legally sold if they meet type approval i.e. equivalent in quality to O.E. previously aftermarket CATs were a waste of money and would pass MOT emission levels (providing no other faults existed) but would often flag P0420 cat efficiency fault (if post CAT sensor fitted) after a few miles?
