Sup, first and foremost, the "twins" reference is well outplayed and I've always hated it.
This car is loud, and without knowing what you're hearing, it's hard to say but I'd bet it's normal. It's lightweight and insulation was scarcaly used to save weight/keep cost down.
The break in period is listed in the manual. I'm going to persaude you to look again and actually read some of it, even though it's mostly all common sense. I bet you will run into something you did not know that is listed in there.
I'm so-so to VW owners, but....
..you chose the right color.
