Abstract

A muffler is provided for attenuating noise associated with flowing exhaust gas and for evacuating condensate from gravitational low points of the muffler. The muffler includes top and bottom plates that are formed to define a plurality of flow tubes therebetween. A bottom internal shell is secured to the bottom plate. The bottom plate and the bottom internal shell are formed respectively to define a siphon tube therebetween. The siphon tube includes a siphon inlet at a location that will coincide with a low point on the muffler and a siphon outlet in a selected flow tube. The muffler further includes a bottom external shell secured to the bottom internal plate and surrounding the bottom internal shell. Condensate accumulating of the gravitational low point of the bottom external shell will be drawn through the siphon tube and evacuated from the muffler.
