If you don't show any loss in power and you did't hear it before, then it must be the intake. They tend to be nosey. If that is not your thing then you should think about a K&N or other drop in for the stock box. Better air anyway.

The stock airbox muffles the dentist drill sound compared to your open air setup....It is normal

It's the turbo getting more air. Your stock airbox restricted a ton of air and now your turbo has a natural whistle to it. Same thing happened when I installed my intake. Also if you have an aftermarket BOV/wastegate, that will be louder too. It's a normal sound.

Don't worry, when I got my Dejon Powerhouse "CAI" I started hearing that too. Now I just think of it as an indicator of how much my turbo is spool, as said in an earlier post.

I haven't heard anything bad about it, but you never know. This was just my experience.
