Abstract
A muffler having a muffler housing with a muffler chamber formed therein includes an outlet stub. In the stub, a channel is formed through which exhaust gases escape. The channel has a throttle location with a smallest flow cross-section and a discharge opening with a discharge flow cross-section. The channel is bounded by a wall. The flow cross-section increases substantially continuously from the smallest flow cross-section to the discharge flow cross-section at least in a section in the direction from the throttle location to the discharge opening. The stub has a fastening location at which it is held in an outlet opening of the muffler housing. The wall is closed continuously over its circumference from the throttle location to the discharge opening. The section of the channel extends in a sectional plane containing a center axis of the channel into a longitudinal section of the stub having the fastening location.
