So i started noticing this noise the other day; it is only really audible at an idle but it sounds sickly.

It sounds to me kind of like a slight exhaust leak but i wont have a chance to get up under the car to find out for sure for a few days at least. Anyone ever have a similar sound/possible diagnosis?
