A muffler for an exhaust system of an internal combustion engine includes a housing with a circumferential wall. At least one resonator chamber () is defined by the circumferential wall and two base walls (), that are provided in the housing. At least one resonator pipe (), with a first pipe end () and with a second pipe end (), is connected to one of the base walls () in the area of a first opening () in the one of the base walls (). In the alternative or in addition the one of the base walls () traverses an interior space such that the first pipe end () lies outside of the resonator chamber (), with the second pipe end () being fixed to the other base wall ().

Muffler for an exhaust system of an internal combustion engine

An exhaust muffler () is provided for an at least partly dual-flow exhaust system of an internal combustion engine, especially of a motor vehicle. The exhaust muffler has a housing (), which encloses an interior space (), with two exhaust pipes (), through which exhaust gas can flow in parallel, and which are each led through the interior space (), and which have a side opening () each within the housing (). A neck body () connects the two side openings () of the exhaust pipes () in a communicating manner to form a Helmholtz resonator with the interior space () of the housing (), which interior space () acts as a resonance volume (). An embodiment, which has an especially compact design and can be manufactured at a low cost, is obtained when the neck body () has two plate-shaped longitudinal walls (), which are in contact each with the two exhaust pipes () and which define a neck volume (), into which the side openings () of the exhaust pipes () open, and which is open towards the resonance volume ().
