Yes, the performance exhaust is the NPP. But, best to confirm with the seller just to make sure the listing is correct. The RPO sticker under the carpet in the rear by the battery should have NPP on it. Plus the exhaust tips would look like this:

To clarify, yes, NPP equipped cars have adjustable exhaust. If there's no NPP on the label, the exhaust is not adjustable. Not all C7s have NPP adjustable exhaust.

Get the compnine.com report on the car.
Don't do the monthly membership, just a $5 for 5 report deal.
Well worth the money. It gives you all the options your car came with OEM, heck it even gives you its date of birth.

On Z06 you just have the visible ones you can see if you look inside pipes, but the others actually have 2 sets of valves. The ones in the pipes and another set ahead of the mufflers.. should be able to see them

The words "performance exhaust" could mean anything with a used car. As suggested, check with the seller to be certain. Enjoy, in any event.

Correct, don't trust what an unknowing or duplicitous sales person tells you about a car. There are forum threads devoted to people not getting what they though they were getting.

Hey thanks for all the tips and info, it shows installed options as 'Performance Exhaust' along with 'Battery Protection Package'
This would be my first C7 coming from a C6 that had the NPP option although i installed the Mild to Wild switch, i'm hoping that can work for the C7 exhaust..
