ABSTRACT:
A muffler outlet part for a muffler to be used in exhaust systems of motorcycles has at least one main body disposed transversely to an outflow direction of exhaust gas and having a center axis, the main body having a centrical first outlet opening disposed concentrically relative to the center axis for the outflow of exhaust gas from an outlet chamber of the muffler, and at least one second outlet opening disposed eccentrically relative to the center axis for the outflow of exhaust gas from an expansion chamber of the muffler, said expansion chamber enclosing the outlet chamber. It further has at least one closing member that is swivel-mounted about the center axis for an at least partial closing of the at least one second outlet opening, and at least one adjustment element for swiveling of the closing member via an adjustment means, which cooperates in a torque-transmitting manner with the at least one adjustment element.
