As the car was not equipped with NPP originally, it would not have the vacuum system which is used to control the bypass valves. In addition to installing the NPP exhaust, you need to install a vacuum system. This consists of vacuum lines from a source for the vacuum (the engine), a vacuum accumulation tank, a vacuum solenoid valve, and vacuum lines to the flapper valves on the exhaust silencers. The Forza 3-way controller could then be used to open and close the valves, but, honestly, at that point you could also use a simple on/off switch as the means to power the vacuum solenoid valve on and off.
If you plan to proceed with this, I can provide more details for you.
