NPP exhaust, 6th vs 5th gen
Just took delivery of '17 SS convertible after selling '13 SS vert to a friend. Both have NPP. The '17 is a whole lot quieter, without any of the sputtering and gurgles of the '13. I expected all of the other differences from reader this forum and other sources, but was very surprised at how far more subdued the C6 sounds. I'm wondering if the '13 was louder by design or whether one or the other is not functioning correctly. Thanks.

Nope it's just quieter inside the cabin. Was too quiet for me so I dumped the system immediately and went MBRP

My 16 2SS w/NPP does plenty of "sputtering and gurgles." I use my paddle shifters to slow down a lot instead of the brakes as long as there's no one behind me who looks like they will run into me without brake lights. I also run my exhaust set in track mode via the settings menu which I found helps.

Never heard a 5th gen NPP sounds as good as mine does. You sure you changed the exhaust to Track mode? It's electronic on the 6th gen vs vacuum controlled on the 5th gen.
Also try putting the back seats down. Definitely increases the loudness. Sent from my SAMSUNG-SM-G920A using Tapatalk

I pulled the fuse on day one and my '16 SS has been pretty loud, about the same as my '13 1LE. The '13 1LE did crackle and pop more...no "snaps" on either, though! lol The 16 is quieter inside, so I roll my window down a lot to "connect" with the car.

So, I'm answering my own question to some degree. Having driven the '17 a bit more since the first post, and trying to decipher the owner's manual, it's apparent that NPP works differently in the various driving modes. It's very quiet in touring mode. If I'm understanding the manual correctly, one can change how the exhaust behaves in the various modes by going into settings on the dash display and getting into the comfort and convenience menu. There it seems you can leave the default setting where touring mode has the quietest exhaust, and the softest MRC setting, or you can specify that in touring mode the NPP can function as it does in Sport mode, etc.

Long story short.
Tour mode = Not very loud...tamer Sport mode = Much louder. Awesome on cold startup. Great on medium to full throttle and open while just sitting. But still fairly quiet while just crusing. Track mode = not much if any louder than Sport on full throttle, but the exhaust valves seem to open up a bit quicker. Will still be quiet while crusing. Your initial drive in Tour mode is nothing like Sport or Track would be.

Responding to SuperSound: Yes, I see that Track setting for NPP and MRC and steering can be forced, as you stated, in any mode using the settings options via the display panel. My question is whether those settings remain in place until changed, or are they limited to one drive. It seems that one can edit each mode (ie Touring, Sport, Track) to have any of the various settings for exhaust, steering, and MRC desired. For example, I can set Touring to have the Track exhaust and steering, but the Touring MRC settings if that's my preference. If I set it that way and then switch between modes, will my changed settings for Touring remain in that configuration until I chose to change them? Thanks.

But you cannot change settings for individual Drive Modes. For example, you change Engine Sound Management to the Track setting. Now NPP will stay in Track setting for all drive modes. So if you switch from Tour to Sport via the Drive Mode Selector, the NPP will be in Track setting regardless. Think of those settings for Engine Sound Management, MRC, and Steering as "overrides". If you take any of them off Auto, you force that setting for every Drive Mode. Just to be clear. There are Drive Modes - via the selector switch just below the shifter. Then there are Drive Mode Settings - changed via myLink, then Settings. Two of the things you cannot change are Throttle Progression and Shift Performance (only autos). Those settings are locked to the Drive Modes. Hope this helps. It's confusing right now but after you play with it in the actual car...easier to understand.

Thanks very much. That's a lot clearer than the owner's manual. So just to confirm my understanding and maybe help others: Mine has a manual trans, so I can alter NPP, steering effort, and ride stiffness (via MRC). If, for example, I go to settings in MyLink and set NPP, to track, steering to sport, and MRC to touring, then I've overridden all settings and nothing will change if I course thru the driving modes. Is that right? Thanks again.
