I find the Engine Sound Management settings on the infotainment screen very confusing. The best I can figure out is:
- Pull up the settings page
- Select a mode, such as touring mode you want to set the exhaust setting for with the driving mode dial
- Then select sport or track on the menu to allow what ever mode you have selected on the dial to now have exhaust valves open for that particular mode, e.g. touring mode

What am I missing if anything?

Hope this helps.

The video is a great help, thanks.

The 2015 is different in that when you get to the engine sound management screen, you don't have the "off" option as in the 2014 video. You will have choices of Auto (default), Stealth, Touring, Sport, and Track. Select your sound of choice on the touch screen to have your preferred sound in all modes.

Is there a drive mode that by default is linked to "stealth"? I figured Track=>Track, Sport=>Sport, Touring=>Touring/Eco/Weather but I may be off.

Good to know! Thanks! I also asked Mike if he would make an updated video for the 2015 model.

The 5 diff settings for NPP were in last years sales guide but did not ake it to production. The only one i want to know about is stealth...what are the valves doing in this mode?...i assume closed 100 pct of the time, even when you hammer it.....

I still don't understand what you do with the touring mode dial and what you select on the infotainment screen. There are only two exhaust positions, but the screen makes it seem like there are four positions: stealth, touring, sport, and track.
What exactly do you do with the driving mode dial and screen select options to pick what exhaust position you want in what driving mode?

Basically on the 2014 there are two choices, to either have the NPP set to be open regardless of the Mode you are in (that is loud whenever you step on the accelerator and then it quiets down when you are not feeding it gas independent of whether you are in Eco, Weather, Tour, Sport or Track) and that is the choice of Sound Management OFF OR the engine management software chooses the setting for the exhaust based on the Mode you select and that is the choice of Sound Management ON. On the 2015 from what I understand, the default is the same as the engine management software chooses the setting for the exhaust based on the Mode you select, OR you can choose Stealth, Touring, Sport, and Track which progressively makes the exhaust sound more aggressive.

So do I understand it correctly that if I am driving in tour mode I can switch to track and the sound changes louder while I am still in motion or do you have to stop in order to change modes? Still waiting for my 2015 to arrive.

 

[WingCon]

So for my 2015, what I would do is set the driving mode dial to e.g. touring, then select sport mode on the infotainment screen if I wanted touring mode to have the sport mode exhaust valve setting?
Or e.g. set the driving mode dial on sport, then select track mode on the infotainment screen if I wanted sport mode to have the track mode exhaust valve setting?
Am I getting this right?

Gm would have huge problem if you could not change on the fly, its fine when you're rolling...

If you are using the default link on your 2015 and change your driving mode to track, which you can do at anytime including while driving, the exhaust will change to being more aggressive. The same is true for the 2014 if you have your Sound Management set to ON.

That should do it.

 

[WingCon]

Thanks. So I take it that for my 2015, there are 4 exhaust valve settings:
- Stealth
- Tour
- Sport
- Track

Correct?

Why dont you look and see? Do you have your car and the manual?

 

[WingCon]

Yup. The manual doesn't go into the detail. It just briefly explains that the settings are there.

You are looking in the supplementary Infotainment Manual, right? That will get you to the proper screen and just follow the video from post #2. The only thing different on the 2015 is the options once you get there. Just touch your choice and a green checkmark will show up in the box selected. Then, regardless of what mode you choose with the console selecter, the exhaust mode will be what you selected from the infotainment screen.

I put this on the 2014/15 differences thread, but I'll just copy my post here. Maybe that will help anyone who might be confused in the future for 2015 models:

1 - leave exhaust sound in factory settings for each driving mode
2 - go into the infotainment screen, thru some more screens, and then manually select the exhaust sound


I think this is a permanent setting that saves (option 2). So, if you decided to do the manual override to stealth as you were pulling into your neighborhood late one night, your car would be stuck in stealth until you went thru the screens again and chose something else or put it back to option 1.

I think most of the time we'll leave it in 1, but will override to loud when we're in the mood. If I can remember, I'll take some still shots of the infotainment screen when I have the car back from the clear bra place she's visiting.
