X-tube and corresponding exhaust system

Abstract

An X-tube (1) is provided, for an at least partly double-flow exhaust system (2) of an internal combustion engine, especially of a motor vehicle, with a housing (3), which comprises two half shells (4, 5) and which has two inlet openings (7, 8) on an inlet side (6) and two outlet openings (10, 11) on an outlet side (9). The housing provides an interior space (12), which is enclosed by the housing (3) and to which the openings (7, 8, 10, 11) are connected in a communicating manner, with a bottom—partition (13), which is designed as a separate component in relation to the two half shells (4, 5) and which divides the interior space (12) into two ducts (14, 15), which are each connected to an inlet opening (7, 8) and to an outlet opening (10, 11) in a communicating manner. The bottom (13) is made permeable for airborne sound and connects the two ducts (14, 15) to one another in an airborne sound-transmitting manner.
