You supposedly get 5 HP increase when it's wide open. It's only loud when you make it loud. It runs quiet most of the time.

I have it and have the Mild to Wild switch sitting on my workbench. I can then control it completely and make as much noise as I want without the wife and put it back to normal when she rides along.
Most people that don't get it, end up asking how they can add it later. If you plan on going big bucks and put on a Corsa or Borla then don't get it.

Personally, I like the NPP Dual Mode Exhaust. The standard Corvette exhaust is much too quiet without it. With NPP you have the choice of quiet or aggressive sound when you want it. My '14 Corvette had it and I was happy with it! My '16 that I have now, did not have NPP so I installed a Borla ATAK Axleback. The axleback cost me $1255 with shipping and a $150 to install. I like the Borla ATAK, but if my car came with NPP I would have left it alone. I think the NPP should be standard on all Corvettes!

If you buy a Z51 or GS, the NPP is standard.
For a street-only car, I would stick with the base car, and not waste money on the NPP... all it does is make the exhaust louder, but in "Touring" mode, my Z51 sounds just fine and doesn't **** off the neighbors quite as much.
However, I'm a cheapskate, and won't spend money on options that are not absolutely necessary.
If money is no object, buy anything you wnat.

Since I bought my C7 off the lot, it came with NPP, and compared to what I would have paid for it on a Porsche, the $1200 (US) wasn't bad. And it sounds really good for when I want to let out the inner child in me. When I leave or return to the neighborhood I put it in Tour mode (quiet) and if I'm out for a drive, I turn it to Sport and let it be loud.
However, it's only loud when you put your foot in it. Even in "Sport" mode, when just cruising down the road/highway, it goes back to quiet mode so you don't go deaf and crazy from the noise.
If you spent all that money for 2LT, another $1300 ain't gonna hurt.

NPP was ordered over 83% of the time in 2014. In 2015, NPP was included in the Z51 & Z06 packages and it went on 90% of the Corvettes that year.
Our local Corvette dealer moves over 100 Corvettes per year and won't order a C7 for their inventory without NPP. In 2014 when one was accidently ordered without NPP they couldn't move it out until December 2015 when it was a full two model years old.
NPP is very desirable. For me, it was my #1 must have when buying a C7.

The car seems loud enough with the coupe top in place that I need to raise the volume up on the radio at highway speeds and I bought the sound reducing pads for the rear deck and behind the seats to get it a couple decibels lower.
So loud with the top off that the radio is useless and the exhaust is probably hard to hear as well.
The average vette owner is around age 60 or so and a loud exterior sound isn't going to impress chicks or neighbors.
I'd like the performance without it being noisy - stealthily fast.
I expect I am in the minority and that's OK.

Forget about the sound for a second and compare look of the standard pipes to the performance pipes which are flared, 1" larger and evenly spaced. I could not live with the look of the std. exhaust after seeing the look of the performance exhaust.
