2008 Escalade - Engine noise while running Sign In

2008
Cadillac
Escalade
6.2L
160k Miles

I am just wondering if any one could point me in a few directions on what this noise may be. It has been this way for a year now and I am now trying to figure out what it may be.

I did have a tune up down 2 days before this video. Plugs/Wires, Air filter, oil change, transmission fluid checked.

Also the Air condition pressure kind of goes up and down, as if I have a power knob and I'm just randomly turning the knob back and fourth. This may have nothing to do with it or maybe it does.

Here is link to the video with the noise: https://www.youtube.com/shorts/hekdGjvMre8

You had this at a shop that could "tune it up" so why didn't you ask them what they thought?

I see CEL on and RPM reading OK for an idle. IDK why they handed you back this car with a check engine light on if you told them that noise was there for a year?

That sounds like an exhaust leak.
