You won't be able to control the valves from the car's software. No wiring harness for them, no software for them, unless you get them from the factory. You could install the NPP muffler and leave the valves open all the time, if you just want the exhaust a bit louder. Might be able to find a take off muffler from someone who went aftermarket.

Check with the maker of the mild to wild switch to see if their controller works with the C8. it works on prior generations. You'll be able to manually open and close the exhaust using a fob.
