Do you have any recordings from the driver seat with the door closed? Not hearing anything crazy in your videos but hard to compare to mine because I don't drive it from underneath.

I did notice that you are leaking muffler bearing grease at an alarming rate.

Hmmm it did not really sound like anything serious. Based on what I heard I would check your idler pulleys to make sure they are in good condition and not leaking grease from the internal piston mechanism. When they go bad they start to make a sloppy ticking sound that can be confused as engine noise. Next I would check for an exhaust leak at the exhaust ports(manifold gasket) and then at the header flange to X pipe. It almost sounds like a mild leak at the header flange. Typically if you have an exhaust leak at the exhaust port the ticking is very sharp but your video(at least how it sounds) seems to be a little more of a sloppy ticking noise.

Thereís a thread I started in the Z06 forum. Took mine to dealer for that sound. Itís the DI pump. Only hear it in my 19 from like 1800 - 2400 and then itís instantly gone.
Took me a while to notice because I was driving the car w/o top and or windows open.

2 new 2019s sound exactly the same.

Non-issue. Send it.
