I had a prototype Windjammer for my 2008 coupe and found it clumsy and not that effective, not to mention pretty ugly when installed. I'm not in a hurry for one for the C7.

What you are hearing is buffeting over the roof, very common. Quick fix, at high way speeds, crack each window 1" (elevates the pressure), and that bad sound is gone...
This surprised me. On my test drive I had the roof off the entire time and was very impressed with how little noise came in the cabin. I did have both windows either completely down or cracked at all times.
