Whooshing noise at high rpms

I have a mk7.5 GTI DSG with a downpipe and tune with about 22000 miles on it. Recently I noticed a high pitched whooshing/whistling at high RPMs. Anyone have a clue as to what it could be? I feel like I've never noticed it before. The car got the downpipe about 5000 miles ago. I also noticed an intermittent low pitched whistle after cold starts before the engine warms up. Here is a clip:

Sounds like the turbo.

Is the diverter valve in use even after the gas has been lifted off and you're coasting at high rpms? I hear the same normal blow off noise that I typically do and it is the same pitch, but this whoosh occurs on throttle, off throttle, at any speed so long as the rpm is high enough.

It's always hard to tell from a video, but all noises in these videos seem to sound normal IMO.

Unless your having other issues (loss of power, surge, ecu codes, etc), don't overthink it.
