Loud. 
I don't generally fool around on the forum but I just couldn't resist. It's a very good question and I'm sure someone like Paul (Talon90) will get us the answer.
I'll be waiting myself.

What does NPP mean? Good Question and thanks
I also do not know exactly what NPP includes or does not include. I would also like to know exactly how it is different from the engine exhaust ports to the back tips.
For example: is it only the butterfly values and controls on the rear? Or is it a stainless steel muffler, and pipes to the stainless manifold?
Are the hangers also stainless, or are they standard soft steel.
Don't let these people make you feel stupid or anything like that.
Its a very good question. I asked my salesman for my C7 what it meant, exactly, and he did not know also.
I would love it if someone who knows this stuff responds with something actually thought-out a bit rather than give non-response responses.
How about it? Can someone tell us what this means in terms of having or not having this option. I have it on my 2014 C7 and on my 2019 C7 and I still do not know exactly what the difference is beyond the butterfly valves and control system.
Who can actually help us?
