A muffler for an exhaust system of an internal combustion engine includes a muffler housing () and at least one exhaust gas pipe group (). The at least one exhaust gas pipe group () includes an outlet pipe () open towards an expansion chamber () formed in the muffler housing (). Exhaust gas introduced via the at least one exhaust gas pipe group () leaves the muffler housing () via the outlet pipe (). A first inlet pipe (), of the at least one exhaust gas pipe group (), has an inlet pipe end area (), which is inserted into the outlet pipe () and extends in the outlet pipe (). A second inlet pipe (), of the at least one exhaust gas pipe group (), is open towards the expansion chamber ().

Muffler

A pipe (), carrying exhaust gas, of an exhaust system () of an internal combustion engine (), with a tubular body () carrying exhaust gas, and with at least one attachment part () separate with respect to the tubular body (), which is added laterally to the tubular body () so that externally on the tubular body () a cavity () is arranged delimited at least partially by the attachment part (), which extends in the circumferential direction () of the tubular body () over less than 360&#xb0;.

Exhaust pipe

A muffler () for an exhaust system of a vehicle driven by an internal combustion engine, includes a gas-tight housing (), a partition wall () inside the housing, an inlet pipe (), a first outlet pipe (), a switchable second outlet pipe () and a resonator pipe (). The a partition wall () divides the housing's interior into a first volume () and a second separate volume (). The inlet pipe and the first outlet pipe () and the second outlet pipe and the resonator pipe are in fluid communication with the first volume. The resonator pipe provides fluid communication between the first volume and the second volume. The second outlet pipe passes through the second volume. The second outlet pipe is surrounded, in a circumferential direction, by the resonator pipe in a section in which the second outlet pipe penetrates the partition wall.

A muffler () for an exhaust system of an internal combustion engine has a housing () with an expansion chamber (). An inlet pipe () extends into the housing () and has an end section () with an outlet opening () to the expansion chamber (). A main outlet pipe () has an initial section () protruding into the end section () of the inlet pipe (). A secondary outlet pipe () has an inlet opening () in the expansion chamber (). A gap () in an overlapping area () between the end section () and the initial section () forms a bypass in the end section () of the inlet pipe (), which bypasses the initial section () of the main outlet pipe (). Through the bypass gap (), exhaust gas flows from the inlet pipe () into the expansion chamber () and out the secondary outlet pipe ().
