I still don't know what the whistling is but I can only hear it when accelerating and driving past something that will reflect sounds such as passing another car or dense foliage on the road sides. The whistling seems to sound like something right out of a science fiction movie. Very hard to describe.

Also, I notice a strange noise right after startup from the engine bay. It'* almost as if the engine is noisy (not banging or knocking) and it goes away 30 sec to 1 min after the car is started. Possibly EGR or ????
