If you remove it you will have to deal with the fact that it is integrated with the engine computer and that could lead to problems. Probably not a big problem with just a DPF. Depends on what system is installed. A talk with Pete's service department might give you some info. Different manufacturers take different steps to make sure the units are not tampered with. They are all made to be disassembled, which means they can all be gutted, which destroys the unit but won't mess with the electronics. Oh, by the way, if you think you are going to see a big performance or fuel mileage gain you are going to be in for a surprise. Oh, did I mention the fines involved if the wrong people find it missing?
