In this case though it still is a no, the NPP exhaust is controlled by the BCM. A non-NPP doesn't have the programming in the BCM to control the NPP system. So yes while you can add all the hard parts you will never be able to get around the programming issue that needs to be addressed in the BCM as GM will not reflash a non-NPP BCM with any other calibration than what is on file for the VIN that BCM is tied to.
