A muffler for use with an internal combustion engine or the like having improved attenuation capabilities together with lower back pressure. The muffler has an elongated outer casing and an inner casing, the tubular ends of which extend beyond the outer casing for inlet, and outlet conducts. The central portion of the inner casing forms a continuation between the ends and has a differently configured but substantially equal cross-sectional area as the ends. The outer casing forms a sealed relationship with the inner casing adjacent the ends thereof. The ...


A muffler for use with an internal combustion engine comprising. a first wall defining an elongated outer casing provided with first tubular ends: an elongated inner casing having a central body portion with second tubular ends said central body portion being defined by a second wall the first tubular ends of said outer casing being attached to form a fluid tight seal with the inner casing adjacent to said second tubular ends, a cross section of said central body portion being substantially equal in cross-section to said second tubular ends but of a diff...
