Patent ID: 7874401

Claim:
An exhaust muffler for an at least partly dual-flow exhaust system of an internal combustion engine, the exhaust muffler comprising: a housing enclosing a continuous interior space; two exhaust pipes through which exhaust gas can flow in parallel and which are each led through the interior space and which have each a side opening within the housing, said two exhaust pipes generating resonance; a neck body connecting the two side openings of the exhaust pipes in a communicating manner to form a Helmholtz resonator with the continuous interior space of the housing, with said interior space of the housing forming a resonance volume, the neck body having two plate-shaped longitudinal walls each in contact with the two exhaust pipes and defining a neck volume, into which the side openings of the exhaust pipes open, the neck volume being open towards the resonance volume, wherein said Helmholtz resonator absorbs said resonance generated by said two exhaust pipes.
