I had two C7's over that gen. First had NPP, and the second one I went standard exhaust and Corsa catback and x-pipe. I was MUCH happier with sound of the second car. Sure, it didn't have the ability to go quiet, but i don't care, I don't really commute in it.

I like the convenience of NPP. It came on the car. I didn't buy an aftermarket exhaust trusting an unknown vendor. Didn't wait to get it. Didn't have to take it to a muffler shop to have it installed. And NPP was less expensive to boot. We like it just fine. Enough roar without a grimace from the neighbors. Plus it can go stealth if need be.

+1. I have a z51, so I have NPP. This is why I am looking at the Borla system. From reading about their technology, their valves operate in conjunction with your valve settings just like the NPP does (once you get the re-flash done by a GM dealer after the install). I run z-mode all the time with the NPP in track mode except when I am interstate driving. i will put it in tour mode, and I want that same capability when I get my aftermarket exhaust.

If you want an aftermarket exhaust on your C8 and you want maximum control of volume and drone, go with the npp 4 valve system from the factory. That way, you can run a 4 valve aftermarket exhaust on your C8.
You cannot run a fancy 4 valve aftermarket exhaust on your c8 (available from Corsa, Billy Boat, Borla, Lingenfelter) unless you have the oem npp exhaust. Do keep in mind most 4 valve options run between about $3800-5k.
I think if you want a straight pipe option and don't care for an exhaust that goes from loud to quiet, stick with the standard exhaust and as stated, invest in a louder more aggressive aftermarket option.
