And if not, then what does "Exhaust Mode" represent in the matrix that RC posted from the bash?
The italicized and greyed items are "if available" (optioned) on the car, but NPP would be an option too. Obviously FE4 isn't going to be on all cars, so MSRC and PTM wouldn't always be applicable, e-LSD is on Z51 cars only and shift modes would be for A6 cars only. What am I missing?

Yes, the valve position varies based on driver mode selection.

So is the fact that it was not italicized as an "if equipped" item on the Driver Mode matrix a typo? All cars will have a variable "exhaust mode" whether equipped with NPP or not?

There are valves for AFM so that is likely what they are speaking of, not NPP.

AFM valves closed when in Eco mode so the car doesn't sound dumb when operating on 4 cylinders.

Snorman

Interesting. So I guess "sport" and "track" exhaust modes are further amplified by NPP?

I would think that would be the case. The chart could just be incorrect and they forgot to italicize or highlight that part.

My guess is that Track mode will keep the NPP valves always open and sport mode will open the valves at a lower rpm than normal mode.

Snorman

If not, I guess there are going to be a lot of freaking valves in the catback.

I'd have to go back and listen to the videos and look at some of the pics to be sure. I sure hope their aren't too many valves in the cat back system. The NPP system is too quiet for my tastes but like the idea of the actuators.

Aftermarket system ASAP

Have a feeling most people will keep it set on Sport or Track.

Matt26

Looks like there are valves just before the mufflers in addition to the NPP valves.

Snorman

Wow...two sets of baffles/valves.

That is correct. If you get the NPP option you will have 4 valves, 2 for econo mode (4 cyn) 2 for NPP when opened.

Also, NPP option comes with an on/off electronic button. No more aftermarket needed!!!!!!!!!!!!!!!!!!!

This matrix is the absolute best marketing tool I've seen yet from team Corvette for selling options!!

Those are just default settings. I understood from previous interviews that user can configure each profile as they want.

In my opinion the NPP is separate from the track mode setting and we are getting them confused. I think the track mode position on the exhaust system can be utilized without NPP.
Could this be possible?

Raitzi

Yes, but I do not think it changes anything on cars without NPP. The other valve is there for 4 cylinder mode.
