Lots of whistle when accelerating

Just wanted to make sure that my turbos aren't about to go out or something...my car only has 5000 miles, but the turbo noise is quite noticeable. Is this a common thing for everyone else?

Turbo-not turbos lol-just one.

I find I only hear turbo whistle when my windows are down, it's a bit too quiet for my taste.

Mine sort of whistles except I only really hear it with the doors closed. It sounds like its coming from underneath the right side of the dashboard and only when accelerating in Sport or Sport+.

The turbos spool up faster in sport mode. Thats why its much more aggressive in sound. I also notice this when i installed bms stage 1. I love the sound man. People are alway looking to see whats passing by. Its starting to become the n20-26 signature sound. Everyone is not use to seeing and hearing a turbo 4 from a 3 series

I like the sound too, it's just pretty loud. (Then again, our turbo makes something like 18psi, so I guess it makes sense.
