Abstract
An arrangement for silencing the exhaust gases discharged from a multi-cylinder internal combustion engine, wherein the exhaust gas is discharged in first and second streams from separate exhaust gas manifolds on opposite sides of the engine and the two streams traverse a different but equal lengthed path to be combined into a single stream to be presented to exhaust system components, such as catalytic converters and separate mufflers. In one embodiment, the streams pass through conduits integrally formed, in part, with through structure of a muffler. In other embodiments, the stream paths are equalized by being passed through conduits formed in closed shells.
