I am wondering if I can get some education on the NPP exhaust, how it works, and options for C7's that don't have NPP, like me. From my research I understand that C7's with NPP have two sets of electronic valves and they operate based upon driver selection. I also have researched that trying to put OEM NPP on a non-NPP car may be problematic due to wiring, software, etc. I have one set of valves just before the mufflers. I cannot really detect a sound difference in any of the driving modes so perhaps the single set of valves provides more performance than sound.
If I buy an aftermarket axle back setup do most of the new exhaust available just replace the single valve set up I have with their own? I assume I would still have single valve operation with their ports but insert my valves, right?
Is it possible that I can buy a bimodal aftermarket set up that would allow me to use my drive control for the first set of valves and then activate some kind of mild-2-wild switch for the second set of valves more or less replicating OEM NPP?
Am I confused.
Thanks,
Russ
