Hissing sound when parked

Has anyone noticed that when you park your truck you hear what sounds like water hitting hot metal and a hissing sound? I’m guessing it’s AC condensation hitting exhaust piping, but just curious if others have heard the same?

My 2021 6.2 Trailboss did that. A/C dripped down onto the exhaust. The cross pipe that joins both sides.

Best I could tell it was the cross pipe so that makes sense! Thank you sir.
