I've just seen some (not really detailed though) of the VOSA changes to the MOT test regarding catalytic converters. I was wondering if any one has any more detail as to how it will affect those of us who have removed the cats or are thinking about (myself as the first project of the year). Do we have to keep them and replace them just for the test? Or does it put the people who make the de-cat pipes out of business? It could get expensive if people have to buy new ones especially on the older cars.
