2017 2ss exhaust

new 2017 2ss with dual mode exhaust sounds super great when i start it in the morning but gradually quiets down. Is there any way to keep the morning growl all the time.

I know when mine is warming up at 750 RPM there is a great bass sound that I love. The whole note is different but as it warms it idles down to 500-550. I love the sound of it with the higher idle.

Pull fuse# 51 in the engine compartment fuse box.

Yes, Go into your settings on your infotainment screen and you can set how the NPP exhaust defaults.

Is that the AFM fuse, or the NPP Fuse?

That's valve timing and fuel control both controlled by the ecu for start up cold only.

It is the NPP fuse. The AFM still works.

You can try doing the fuse pull, which keeps the exhaust valves open: http://www.camaro6.com/forums/showthread.php?t=441499 . That should help keep your exhaust from quieting down as much.

This should help. Read your manual; If it has some sort of stealth mode make sure it's turned off. Certain driving modes will also change the volume output as well such as track or sport modes. If all else fails, headers.
