Not exactly sure, but it will have a big effect on the signals from the rear oxygen sensor, which will change the fuel mixture, set a check engine light and make it run very inefficiently. You will be emitting more pollution into the air and modifying the vehicle in such a way as to actually make it worth less. Really not a good decision.
