2020 Camaro NPP Exhaust

I recently purchased a 2020 Camaro SS Convertible and it does have the mode button for track, sport etc. I have single tailpipes on each side not dual but I see butterfly valves on the pipes going into the muffler. This doesn't seem to be what I see for having NPP exhaust, it looks to be that if I had it the butterfly would be on the second tailpipe on each side. I'm considering getting an aftermarket axle back system but I want to make sure I get the correct one.

Those are AFM valves in the picture not to be mistaken for NPP valves. If you have single tip exhaust then your car doesn't have NPP.

Yep, AFM valves.

May be tough finding an exhaust with AFM integrated. If you want to keep it you’d probably have to go axle back and cut right after the AFM valves
