Picked up my new car Friday but dont understand the exhaust, how do I make louder, I sit in the drivway and turn the control to all the differnt mods but the exhaust noise stays the same, what am i missing here. Did I pay for something that really does not work ??

If you have the NPP exhaust, you should hear it get louder in sport and track. If you are not sure look at the two outside exhaust pipes to make sure you have the dampers and that they go open in sport of track modes.

Sounds like you don't have the exhaust linked to the drive modes.

Go to Settings, then go to
Vehicle - Personalization menu
Vehicle - Driving mode
Exhaust - Engine sound management
Exhaust - Off

Indy-hp

In the settings menu of the infotainment screen, go to vehicle settings/exhaust/link to drive mode.

Which is what some of us do. Not everyone wants it loud all the time. He might want it linked.

Hopefully its not linked for some reason. Mine was linked by default though. Sport and track made an obvious difference even idling in the garage. Hopefully the dealer didn't screw up and forget to order it with npp.

It's not loud all the time except in Sport and Track.

Woodson

It is if you do it your way.

At idle the difference is noticeable but not much. Under acceleration it is.
Even with sound management set to off the system will close the baffles sometimes.
If you want to be able to totally control it manually you can pull fuse 42 under the hood. Here's a good thread by forum member Theta:

Good info. I did not know you can change the settings in the menu.

Thanks for the help, will go to the settings and try what was suggested.

If you have a 2015 Z51 car you will have the NPP exhaust. If you have a base car, the NPP is an option.
If you have the NPP, you will hear a difference (even at idle) when linked to the drive modes.

Does it work the same way with the A8 and M7? I drive in sport all the time and have sound management tuned off and with the A8, it goes quiet once you reach about 35 mph unless you put your foot into the throttle.

It's not too loud to me regardless when inside the car. On the outside for a stock car it's decently loud. It's too quiet sitting next to my C6. You can't even hear the Stingray

The automatics go into AFM (4 cylinder) mode all the time, which activates a different set of valves that you can't control manually. Only way to prevent that in the A8 is to drive in paddle shift mode.

Here is everything a Stingray owner needs to know about how the NPP exhaust works: https://www.corvetteforum.com/forums...ck-result.html

RTFM people, RTFM. Almost all of this information is in there. If you spent $60K or more on a car with a zillion customization settings, take the time to learn about all those options.

Not a very forum friendly response. You could make the helpful suggestion to read owner's manual, even providing page numbers, if you have them, without the suggestive swear word. Hope you have a better day and a better attitude today!

I have the M7, and a couple times driving around in sport like a grandma it did get quiet on me. Not sure if it glitched or it closes after a bit if you're driving slow. I woke it back up by switching to track mode and then back to sport mode. If it does it again I'll try just jumping on the gas and see if it kicks in.

I don't think its going into 4 cylinder mode as I'm still accelerating normally.
