IF I had to guess I'd say its the flapper valve on the 2nd exhaust pipe. You could clamp(pinch with a rag and vise-grips) the vacum line shut and start the car. The vacum hose is just under the exhaist tips (outer pipe - LEFT).
Ok - so crimping that vacuum line eliminated the sound entirely. Does that mean that it is entirely benign or do I need to have it taken care of?
