Has anyone dissected a C7 NPP muffler? Wondering what the inlet and outlet diameters are. Also wondering if the "open" side is a perforated tube like most C6 NPP or if it is a solid tube like C6 ZR1 and 12-13 NPP.

I'm curious, because I've been considering a C6 ZR1 exhaust swap on my 2007 Z06. But I ran across a smoking deal on C7 Z06 mufflers. I don't think I'd have much trouble manually wiring an open/close M2W type switch to actuate the butterfly valve on the C7 mufflers. Just curious if anyone has tried that yet.

and yes, i did search, but found nothing... If I missed it, please direct me. TIA for any insights.

Might be worth trying once you get the hangers in the right place. Assuming you get them hanging in the right spot I'd imagine an exhaust shop could figure out the alignment.

Two points to consider.
NPP is just an option code that exists to order a bi-mode exhaust system for cars that don't have one as standard equipment. Bi-mode is standard on the C7 Z06, C6 Z06, and C6 ZR1. It'll make your future investigations simpler by referring to all those mufflers as bi-mode.

If you found a deal on C7 bi-mode mufflers, give it a whirl. Somebody has to be the first to try stuff and you could be the one.

However, since you already have bi-mode on your Z06, why not just do the muffler mod that covers up the internal perforated pipe? I'd guess the labor time/expense would be similar and you'd have no purchase cost or electrical to figure out.
