Low, loud growl on hard acceleration

Haven't seen anything quite like this here before.

Low loud growl, sometimes "pop" on hard acceleration. Not pinging - much louder and lower.

Any ideas?

Yeah, that, too. Seriously, though, it suddenly got much louder than normal engine noise, and the corresponding vibration is pronounced. Stops after a few seconds.

Solved

Problem solved. Bent exhaust shield (where it makes a right angle turn at the bottom -- hit on something...) Hard to believe this could make so much noise, but after bending away from pipe, noise went away. New part ($65) on order.
