Also there is absolutely no diff in engine. Only programming and exhaust from Y-pipe back. Not worth trying to change this,as it is 3 grand for pipe and impossible to reprogram stock ecm w/o a valid vehicle ser# from an identically equipped truck. Not sure if an H&S or similar tuner would do it--maybe.
