Abstract: A muffler for an exhaust system of an internal combustion engine includes a muffler housing with a peripheral wall which extends longitudinally in the direction of a housing longitudinal axis. At least one base wall is surrounded by the peripheral wall or/and retained on the peripheral wall and delimits a chamber in the muffler housing. At least one base wall opening is surrounded by an opening edge region which is bent at an essentially plane base wall region of the base wall essentially in the direction of the housing longitudinal axis. The at least one base wall opening receives an exhaust pipe with a press fit in at least one base wall.

Abstract: The present invention relates to a muffler for an exhaust system of an internal combustion engine, including a housing having at least one absorption chamber which is filled with an absorbent material that has an absorbent effect for airborne sound, a straight-through pipe that carries exhaust gas during operation of the muffler and passes through the housing, and at least one blind pipe that is connected at one end laterally to the straight-through pipe and is sealed at the other end. The blind pipe has a wall that is acoustically transmissive for airborne sound in an area running in the absorption chamber.
