An exhaust muffler includes a housing having a rectangularly shaped hollow interior without fiberglass or other packing. An inlet tube and a first outlet tube extend through one side wall of the housing, and a second outlet tube extends through an opposite side wall. The inlet tube extends to an inner end disposed at a central region of the interior in a position facing away from a forward end wall of the housing toward an opposite rearward end wall, while a baffle assembly within the interior includes perforated partitions that define two Helmholtz chambers, as well as a first passageway from the inner end of the inlet tube to the first outlet tube and a second passageway from the inner end of the inlet tube to the second outlet tube. The baffle assembly includes first and second plates disposed within the first and second passageways to split the flow of exhaust gases.

[ What is claimed is:] [1.] An exhaust muffler, comprising;a housing, the housing having opposite top and bottom walls, opposite first and second side walls, and opposite forward and rearward end walls that enclose a hollow interior of the housing;means in the form of an inlet tube for conveying exhaust gases into the housing;means in the form of first and second outlet tubes for conveying exhaust gases out of the housing; andmeans in the form of a baffle assembly within the housing for defining multiple paths for exhaust gases to follow and multiple Helmholtz chambers for the exhaust gases to encounter as the exhaust gases flow through the housing from the inlet tube to the first and second outlet tubes;wherein the inlet tube extends through the first side wall to an inner end of the inlet tube that is disposed at a central region of the interior in a position facing away from the forward end wall toward the rearward end wall, the first outlet tube extends through the first side wall, and the second outlet tube extends through the second side wall;wherein the baffle assembly includes first and second partitions extending between the top and bottom walls of the housing that define first and second Helmholtz chambers, a first passageway from the inner end of the inlet tube to the first outlet tube, and a second passageway from the inner end of the inlet tube to the second outlet tube; andwherein the baffle assembly includes means for splitting the flow of exhaust gases in the first and second passageways, including a first plate extending along the first passageway intermediate the inner end of the inlet tube and the first outlet tube and a second plate extending along the second passageway intermediate the inner end of the inlet tube and the second outlet tube.
