Is this sound normal?

2017 base wrx here with just a cat back exhaust. Got it about 2 months ago and only notice a couple weeks ago that the turbo noice became more pronounced. I don't know if it actually changed or I am geeking and it sounds the exact same. It sounds partially like a vacuum/boost leak but I don't notice any lost of power, weird turbo pressure or have messed with anything between turbo and intake. I also don't stall or run weird in any way. Just want to make sure this sounds normal or I blew off a hose somewhere. I also got the p0420 code recently unknown if it has anything to do with this noise.
