my guess would be that tin metal (gas tank heat shield) is vibrating
on the exhaust when cold ?

Is that a wierd buzzing/vibration sound? I get that too, although it doesn't last as long as yours (only about a second or two). It only occurs when the car hasn't been driven for a while and unlike your observation, I've noticed that it's more prevalent in cold weather. In the summer, I don't really get anything....which is also the time I took it to the dealer to get it checked but they couldn't find anything.
