MR, in the UK there was uproar a few year ago at diesel owners removing diesel particulate filters when they failed to avoid the high cost of new ones, the same will happen with OPF in time. (Do you know our OPFs will need replacing in 60,000 to 100,000 miles at owners cost).

That is when they introduced the "visual inspection" of emissions equipment to the MOT and also made it illegal to sell remaps to specifically remove emissions equipment. So the MOT relies on visual checks and lack of any CEL. No OBD check's are included...
