Abstract
A muffler assembly for a vehicle includes a housing at least partially defining an internal cavity and having an inlet and an outlet. The muffler assembly includes an outlet pipe that has an inlet end open to the internal cavity and an outlet end open at the outlet of the housing. A siphon tube is in the internal cavity and has an inlet opening adjacent an inner surface of the housing and an outlet opening in fluid communication with the outlet pipe between the inlet end and the outlet end of the outlet pipe. The siphon tube is configured to remove condensate from the internal cavity when a predetermined pressure differential is established between the inlet opening and the outlet opening.
