The high pitched whine with the Stratmosphere intake is just the Supercharger sound being uncorked. The sound is barely audible in the cabin, especially if you have the radio on at even a low volume. You'll know the intake is still there, but it's nothing obnoxious. That said, I love my Stratmosphere Hyperflow intake, probably the first intake I've run in 10 years that actually installs as easily as they claim it does and after running at the strip I have to believe that it actually makes a slight difference in performance. This is especially true on cars with tuned ECUs.
I can't speak to the A.W.E. intake since I've never seen one or heard one, but I absolutely love the Hyperflow.
Hope to do some datalogging with it as soon as I get hold of a vag-com for a day or two.
