ABSTRACT:
A muffler for attenuating sound in internal combustion engine exhaust systems comprises an inner shell subdivided into an inlet chamber and an outlet chamber, inlet and outlet tubes for the muffler opening into the respective chambers, and an outer shell surrounding the inner shell but spaced transversely from it to provide a passage between the outer periphery of the inner shell and the inner periphery of the outer shell through which gas flows toward the inlet end of the muffler from the inlet chamber to the outlet chamber.
