Hi all,
Question regarding the NPP exhaust and related touring/sport/track modes:

If you install an axle back exhaust that does not have the NPP valves, meaning you are disabling the actuators, what does this actually disable? Obviously, the sound of the exhaust is one mode, but what else changes?

- Is the engine noise functionality of Touring/Sport/Track now disabled?
- Is the throttle response that changes when switching between
Touring/Sport/Track disabled?

What is the "default" setting with the actuators of NPP disabled? Hopefully this makes sense.

Thanks!

when you change axle backs you have to cut out npp including the valves, so no it won't work and there are no valves to open or close at that point. your driving modes won't be effected except for the sound portion. Everything else will be the same.
