I am getting a P0420 code on my MG ZT 180 Auto indicating there may be a problem with the CAT. The car has had a full service and I have replaced both VIS motors that where faulty. The car also just passed it MOT today.

Would a bad CAT cause fuel economy issues? The back box is rusting on the outside badly so will need to be replaced anyway

I don't want to buy an OEM Exhaust as this is way too expensive.

Can somebody recommend where I can a good quality aftermarket Exhaust and CAT

Regards

Desmond
