If the DPF is removed completely it will fail an MOT, they will look and see whether it was meant to have one when it left the factory, if it did and it isn't there it will now fail, you can have them cut open and the internals removed, then welded back up to look standard but there's nothing there, as long as it doesn't smoke too much when they test you should be fine, I've been told it will smoke more when it's mapped, whether that is completely true or not I wouldn't know as I am not mapped yet, but I am looking at running a straight through exhaust through new unrestricted boxes..
