That is certainly interesting. Can't see what the reasoning would be behind it unless you somehow ended up with an Npp-wired and enabled system (RPO) with a non-NPP physical exhaust as a swapout.
Or, they've just streamlined the CCM/ECM process, but will confuse many people when the settings don't change anything.

Well hell, that's just going to complicate things down the road.
As of the last time we all put our heads together on this (April), we (meaning several of the Tech Contributors here) hadn't seen this.
I don't know whether this will be a positive or not, as in your case, you don't have the wiring. Sort of like the tow hook addition - great to have those added without knowing because they actually served a purpose. Changing over to a flat (single-code CCM) system without wiring (and without any ability to retrofit that wiring from an OE level) is just a recipe for trouble tickets from buyers wondering why the sound doesn't change.
Watch this go in the direction of BMW with the cabin sounds... They can take my M-Active sound and shove it. Thankfully, it can be coded out, but you can see what I mean.

From the infotainment system I can select if I want the exhaust to be set to sport ,track ext or be based on the driving mode. I will take a pic of it later today and post it. I was supprised I didn't have npp exhaust since I could select the way it functions on the screen
Made me wonder if GM may of been planning a dealer upgrade path - for sometime in the future.

I'll back off of the assumption earlier regarding the other device. If, in fact, GM has streamlined the ECM/CCM interaction and part numbers with SPS code, there is an ability to sniff CAN data (if it does exist on non-NPP cars).
Perhaps I've underestimated them in this case, but sadly, this will only apply to 2015+, and it may still not work like that.
I don't have any hard feelings or feelings of competition toward them or the product. After working with these systems and modules for a long time, it's nice to know there's some other poor guy that's been banging his head over the same thing.
The difference will remain in the way they work - if they can truly integrate into that ESM menu that GM so kindly placed there, then there's a way to give the factory-level of integration. I don't see the wire actually being there, but hey - it may very well be!
My design, however, is geared toward a manual on/off switch. Many NPP-owners want the ability to switch on and off immediately and skip the menu. It's all about needs/wants, and that's what's great about multiple products. Lord knows my project is small-scale, and couldn't keep up with high levels of demand.
Anyway, I'm still befuddled by this news. Seems like a very cheap solution to do this to customers... I hope that Mike is correct, but from what I've seen on a late-production 2015, the wiring still isn't there, so no way to do a factory retrofit without some intensive work (which is beyond the normal service center scope).
