Just started happening a couple days ago. Not too fond of the noise at all! Freaking me out. Any Clues? Noise really only happens when I put the her in a Reverse or a Driving gear. Stays quiet in Park and Neutral. Also stays quiet when I'm on the move, but once I go below 1k rpm, noise starts again. I'm going to assume probably some part of the exhaust is loose, but I don't know where or how to begin to diagnose from where it's loose.
Have a listen....

Any Input and Suggestions are welcomed! I'm not too mechanical other than brakes and minor engine tune ups, so please speak to me as a layman. Thanks guys and gals!
