Engine pffft or tiny backfire when shutdown in exhaust

[cpcolt4545]

So it started today.. when I turn they key off it back it sounds like a tiny back fire or rush of air in exhaust. Truck is fully deleted. 2015
I'm scratching my head because I have no clue what it could be..performance is still there.. nothing else going on...

Is the Exhaust brake on?

Video or audio clip available?

Mine makes a sound like that when i shut it off with the exhaust break on. I assume its the turbo doing something.

sounds normal to me.
my 4th gen did this exact same thing, never gave it a thought. probably just the VGT doing a thing.
