Close exhaust actuator before start
Is there a way to close the exhaust actuator on a 2018 ZL1 before I start it?
Thanks.

2. Wait for infotainment to boot up. 3. Go to Settings > Driving Mode > Engine Sound Management > set to STEALTH. This will close the NPP exhaust valves. 4. Start the car. |

Forgetting to leave in stealth mode before parking for the night, eh? It should become habit pretty soon.

I would just put it and leave it in stealth mode all the time. Problem solved.

If you shut it off in stealth mode when you initially start it the valves will be open and then shut after a few seconds so it is a bit loud at first. I never tried it the way Gunkk described

Gunkk nailed it!
Mine is in stealth and starts quiet every single time. |
