Does anybody really know the detailed specs about the different driving modes including how exactly the dual mode exhaust behaves?? Lots of info on the web but it is all pretty vague IMO.
Thanks!

Still don't know what the difference is with the performance exhaust between eco and tour. It is obvious when you turn it to sport. Wish I could keep that sound in tour mode. Does eco do something to the exhaust that actually enhances fuel economy?

none - eco, weather and tour are all the same - closed unless you stomp on it....

Ok, somebody screwed up on that matrix above. Should say 'on' or 'off' for each mode listed. duh.

You can keep that sound in all modes if you turn the sound management off in the settings

I think there are some differences between sport and track (should = Sound Management Off in the settings). I believe sport mode will close the valves on the highway under light load to minimize droning. That may be why some complain it gets quiet sometimes.

Thanks Ken! For usual driving, I like the ride in Touring mode, but like the sound of Sport Mode. Now I can have best of both without switching modes all the time.

Thanks all for your replies. I really like being able to control the exhaust either with the driving mode or just all outlets open all the time (through settings menu). Sounds great!

Ok, I went to 'settings' and there is no option for sound management. Any suggestions?

OK, found it. You can't do it from the instrument cluster 'settings', you have to do it on 'settings' on the infotainment screen. Was looking in wrong settings menu.

There are definitely differences between Sport and Track Exhaust Modes. The difference is obvious even when revving the engine from a stop. In my opinion, Track Mode sounds much, much better than Sport. I wish I could skip Sport Mode and, with the NPP slaved to the Mode Selector, switch between Touring and Track Exhaust Modes only.

I used to drive almost exclusively in Sport Mode but now I mainly stay in Track Mode. Not only do I like the sound better, but I enjoy the throttle blip on the downshifts and increased throttle response. I've always had my steering permanently selected to Track Mode.

Even at idle, there is a difference between the exhaust sound for Sport and Track modes. Try it.

I hear no sound difference between Sport and Track but I have a manual so I never go into V4 mode and get the primary valves to close. What is different is the throttle response which may be why it sounds different in track mode to you.

It's not related to AFM. As stated above, one can hear the difference at idle. At idle, we are all running on all 8 cylinders. Additionally, the throttle is more responsive in Track Mode. Because I prefer manually shifting with the paddles, I don't experience AFM cylinder deactivation.

When in Sport Mode, it sounds like a well tuned musclecar. In Track Mode, it sounds like a European supercar.

There are four distinct exhaust modes for the NPP system, ECO (used in Weather and Eco driving modes), Touring, Sport and Track.

Sport and Track are distinct and different NPP modes (pg 9-40 of the owner's manual), and I can hear a difference.
