Is this what the "performance exhaust" option is? I was building out a 19 C7 and this option came up but it doesn't have any other details. The cost is about $1,000.

Yes it is. It sounds great and looks great!
You control the modes by the dial on the console or in the infotainment screen. It is programmable.

It's an option you don't want to pass up Max. Plus, it's actually cheaper than the brand name aftermarket exhaust. It has different settings, stealth, normal, sport, and track. You won't be disappointed in the system.
yep totally worth it. A loud exhaust is great... most of the time, but not always. So the ability to change the exhaust level via a knobil is fantastic. Add the Borla X-Pipe and it’s even better.
I'll mention that some dealers play it smart and order NPP all their base Corvettes since it's only a $1,195 option. Peanuts on a $57K and up vehicle. Check out MacKulkin's base 1LT inventory for an example of this..

Yep, cost the same for my 2014 C7 Z51 as now but came standard with my Grand Sport. You'll find it comes standard with several models, have to check.
MORE INFO THAN YOU MAY WANT!
I had the NPP option in my C6 that I added a toggle switch so I could control when the mufflers were "essentially" bypassed. I bought NPP for my 2014 Z51 and as mentioned came standard on my Grand Sport. However my perspective on "must have" is a bit different than some others, I'll explain. If you look at forum Threads about adding an X-Pipe or removing the muffles you'll see for some folks it's not as aggressive a sound as they would like! In fact, IMO it's not as "good a sound" as you can buy from Borla (who have several sound options) and others. However in addition to the installation cost they sell for more than $1000.
NPP operates about this way. Depending on the Driving Mode control setting the mufflers are "mostly" bypassed at certain rpm's. You can also set them to always open as if in a specific drive mode regardless of the drive mode setting. For example, I have mine set at "Always Track Mode." So although I now drive in Sport Mode and was Driving in Touring Mode the butterflies controlling the system always opened at ~1700 rpm. The mufflers are "essentially" bypassed at ~1700 rpm. Below that level the butterflies controlling the system are closed and the car is "less loud." In the more normal setting Tour Mode, they open later at ~2500 rpm.
There is a bit of a contaversey about them always being open at Track Mode setting BUT I find there is a distinct sound change at ~1700 rpm AND folks who think they want more control who buy a Mild to Wild switch agree it does not stay open all the time in Track Mode. Also some remove the fuse that controls the system so they never close. However that may cause an objectionable drone at highway speeds depending on what you think is objectionable!
Others add what is called and X-Pipe. Actually all Vettes in recent years have had an X-Pipe as does the C7, with or without NPP! These devices sold by Borla etc actually remove the Secondary CATs so add more sound.
Bottom Line
I have NPP and it's acceptable set at always Track Mode. I find no need for an "X-Pipe" or a Mild to Wild switch. But, IMO, it does not sound a good as a friend who had a Bola system or the FlowMaster muffler and duals I had on my S10! I also added other mufflers and made and fabricated an H pipe for my 1st Vette, a 1988, that sounded better. To each their own!

Jerry. I have mine set to sport only, sounds good at take off, but they do close at some point/rpms when cruising. However, I kinda like it that way. As I've grown more mature (re: old ) I've found that cruising without a roar from the exhaust is right up my ally.

Performance exhaust set to track mode and doing a cold start is the best.
I warn people around the car that it will be loud and they still jump when it starts...must be he pulse of the sound wave radiating through their body.

Exactly! Exhaust drone while cruising on the highway gets old quickly. My last car had high flow cats with an aftermarket dual exhaust plus muffler
I loved it... 80% of the time, the other 20% of the time your thinking: why did I ruin my car I was bit worried about the Borla X-Pipe having that effect, but once the valves close the car goes back to sounding like stock.
