110 or higher starts to humm pretty loud. Just air moving over the car or through the scoop and off the fenders I guess. Our car arent really built like airplanes!

If you fold your mirrors in, it should stop.

My 06 wrx wagon does the same thing. It starts anywhere from 90- 100+. A real pain in the A$$ to hear at those speeds.
