But I am really anti-deleting features from car, unless it's emissions "feature"

I'm not saying that no NPP vales are going to be as quiet as the stock setup in stealth, it won't. But not having NPP valves isn't much different with headers than without at idle and part throttle, its really full throttle that it becomes very noticeable.

I have the AWE Track Exhaust with link pipes. At first i didn't regret it however I realized afterwards that i have elderly neighbors. Not just that but my county started enforcing exhaust ordinances due to increased side show activities. So now i miss my NPP. LOL!

I bet, the track exhaust has no mufflers at all.

I'll be installing the AWE touring with NPP when my Zl1 gets built. I've heard shops tell me they don't make them but AWE contacted me to make sure I wanted the npp and they're making it within a few weeks time.

There is no AWE version that has NPP, I just confirmed it with AWE a few minutes ago.

That is a typo or incorrect ad. There is no NPP version.

You must have missed the part where AWE contacted me directly to make sure I wanted the NPP

You may have missed the part where I said I just got finished contacting AWE directly and John Voss told me there is no version with NPP valves

There are no NPP valves in the photo.

Judging from previous discussions here that AWE team members were part of, they had absolutely no plans to develop an NPP (valved) version and took every opportunity to highlight their automatic drone cancellation ("180 technology") instead.

Thus the likelihood that this is an erroneous ad is very high. I don't see any new, NPP compatible exhaust at their website either.

Turns out you guys were correct
I received an email from AWE after submitting a question since this post. I told the folks at American muscle they need to update their advertising products that don’t exist. Sucks but hey they made it seem like it was an actual thing. Moving on lol

Well, in all honesty, AWE's exhausts are almost universally liked, they are apparently a high quality solution.

I for one am not ready to surrender NPP, because I like that I can have different sound profiles even with the same throttle input, rpm and speed that I have manual control over (so if ever change out my exhaust, it will likely be for a Corsa NPP).
