Abstract

An exhaust system for use in combination with a combustion engine. The exhaust system includes a silencer having an outer casing that defines an interior and an internal construction within the interior and co-extruded with the outer casing so that the outer casing and the internal construction constitute a one-piece extrusion. The outer casing has a length in a longitudinal direction and a substantially uniform cross-section in a transverse direction. The internal construction has at least one wall that extends the length of the outer casing to define with the outer casing at least two longitudinal chambers within the interior of the outer casing. The wall has a deformed portion and passages through the deformed portion so that the silencer has a path through which gas flows from a first of the two longitudinal chambers and through the passages into the second longitudinal chamber, resulting in noise reduction for the combustion engine.
