it doesn't. and thank god, I LOVE the sound of my F30 at WOT.
And with the Performance Exhaust, I love the low rumble at 1800-2200rpm on the highway. I actually drive slower so I can enjoy it. it's weird, I know.
But I'm weird about this car, I'm staring at it right now from my 3rd floor bay window, and deliberately park it outside for that reason...what has BMW done to me. #firstbmw
