Yeah, wind noise in the 2011/2012 Mustangs while driving at speed is terrible. You either have to have the window cracked or just opened about 1/4 inch or you can't even hear the radio.
I have the side window louvers on my GT/CS and am looking to replace with the louvers that you remove the glass and insert. I have seen some of these that have functioning vents that open and close. (Like the old 69s). This may help the wind noise a bit, but at the very least it will provide better air flow in the cabin.
