I have the same noise not the whistle it more liek a "WHOOO" noise consistant when driving and an 40-60mph range is when it really noticable. I have a 6 speed and i hear it. I thought it came from the wing I just knew it was back there somewheres. It annoying without music but with radio I'm fine. Its not loud but an low annoying winding noice. Hope there will be a solution thanks
