An exhaust muffler comprising an outer body having open ends which are enclosed by heads. An exhaust gas inlet tube is mounted in an opening in one head, while an outlet tube is mounted in an opening in the opposite end. The adjacent ends of the inlet and outlet tubes are spaced apart within the body. A baffle is secured to the inner end of the inlet tube, closing off the tube, and the peripheral edge of the baffle is spaced from the body to provide an annular passage. Exhaust gas and sound energy entering the inlet pipe are directed outwardly by the baffle through perforations in the tube, and the gas then passes through the annular passage and is discharged from the body through the outlet tube.
