Yes it does sound metallic.. Not like an air whistle, as I would ASSUME if it were an air whistle, it'd be louder the higher RPM.

I'll check some youtube videos. I tried taking a few, but I think it was a bit too windy... lol

I hope it's not the CCV, I saw a few DIY's, and it looks like a BITCH to replace..
