I'm having problems with my dpf, the cars done 130k and the dpf is coming to the end of life, I kno the best option is going to r-tech and having them do the dpf removal and remap, but my question is iv seen a forge dpf removal pipe for £150 , I kno about the mot laws changing etc but I'm not too fussed, I want to know how safe it is to run the car with the dpf removed and not mapped out etc?
