For background information I've got a 2SS M6 with dual mode exhaust and magnetic ride control suspension.

1. How exactly does the NPP exhaust work? As far as I know, there are valves that open and close, (at the muffler?) that activate at a certain point. What exactly engages these valves, speed, rpms?

2. What is the difference between turning traction control off and turning stabilitrak on? Also, what specifically changes on the car whenever you activate these features?

3. Does anyone know what EXACTLY changes with each drive mode?

4. How does the magnetic ride control work?

To be clear, I'm aware of the general functions of these features, but I'd like to know more specifically what happens and how they work.

Thanks
