Whats this hiss sound when letting go of throttle?

Hello fellow VQ owners I have noticed this subtle hissing sound when revving and letting go, the sound immediately stops at idle, its like sounds like air hissing or something like that, i have no codes, i have stock cats, sorry its not that clear in the video but if you hear it does anyone have any idea what it can be?
I have a 2016 AT 370z with 73K miles
