Abstract
Provided is an exhaust gas retreatment device for an exhaust system of an internal combustion engine including a housing, in which an exhaust gas retreatment element and upstream thereof a silencer device are arranged, an inlet gas path leading from one housing inlet to an outlet of the exhaust gas retreatment element located in the interior of the housing, with an exhaust gas path following the inlet gas path which in the interior of the housing leads to the silencer device and/or through the silencer device as well as to a housing outlet. A cost-effective design can be achieved if the inlet gas path has a higher gas tightness than the exhaust gas path and/or if components of the exhaust gas retreatment device limiting the inlet gas path have a higher material quality than components of the exhaust gas retreatment device only limiting the exhaust gas path.
