Wondering... what is causing rough idle and accelleration from exhaust?

[lennylen]

Hey all,

I was driving my '05 zhp 330ci down a very smooth road on my way home from work and I noticed a low hum from the engine getting louder and louder. Turned down the must and slowed down and noticed that the engine had a much rougher and lower sounding idle than before...

Curious...what could be the cause?

It's hard to explain the sound so I took a couple vids. Needless to say I will be limping it to the mechanic tomorrow.
