What's making this metallic ping?

[RND1]

I know metal pings when cooling down, but this metallic ping is louder than on any other car I've ever owned. It also goes on for a long while. The difference is it pings while the engine is running and while driving so I don't think it's normal? Any thoughts as to what's causing this?

Took this video right after shutting down from a 45 min ride.

Sounds like the exhaust system cooling down to me.

Thanks Mike. If it's exhaust, would it ping when the truck is running and driven?

My work truck (2015 Silverado) does when I pull into a gas station and it's idling. It's not super loud and I can't hear it while I'm going down the road. Yours makes some pretty loud popping noises though. I think it's exhaust system related but that's about all I can say

This is normal. Louder than on most vehicles.
