When you're listening outside your window(s) while driving you may not be able to pinpoint the exact location of the sound. I didn't know where it was coming from either at first (front, back, etc.) but it did sound louder on the left side. It's only when I did some research online that I figured out it was probably the exhaust flap.

Try the twist-tie mod, it takes about 3 minutes and you can remove it if it isn't in fact the exhaust flap.
