The thing is I like how quiet the E39 is (most of the time I drive with the windows closed and the AC on). I also take my family on long road trips and the last thing I want is extra wind noise while driving for hours on highway speed. But if it doesn't add wind noise then I will install it because I like the looks of it, and I like to photograph my car often (just for fun).
So if anyone has installed this and has experience with it, I would like to know for sure if it adds wind noise or not.
