Weird humming/"mooing" sound from exhaust side of engine on my 2012 535i‏

There's a weird humming sound from the exhaust side of engine. It's getting so annoying. I dont think it's normal. I took it in to check a couple times and the SA at Crevier told me it's normal. Please see the video clip below (it's not my car but it's exactly the same problem).
