An exhaust gas heating assembly for an exhaust gas system of a combustion engine includes a heating unit housing which accommodates a flow of exhaust gas. A plurality of heating units are disposed in the heating unit housing and are elongate in the direction of a heating unit longitudinal axis (H). Each heating unit has first and second heating unit longitudinal end regions. The heating units with the first heating unit longitudinal end regions and the second heating unit longitudinal end regions are supported in relation to the heating unit housing via a support structure. At least one heating unit by way of the first heating unit longitudinal end region thereof or/and the second heating unit longitudinal end region thereof is supported on the support structure so as to be movable in the direction of the longitudinal axis (H).

An X-tube () is provided, for an at least partly double-flow exhaust system () of an internal combustion engine, especially of a motor vehicle, with a housing (), which comprises two half shells () and which has two inlet openings () on an inlet side () and two outlet openings () on an outlet side (). The housing provides an interior space (), which is enclosed by the housing () and to which the openings () are connected in a communicating manner, with a bottom&#x2014;partition (), which is designed as a separate component in relation to the two half shells () and which divides the interior space () into two ducts (), which are each connected to an inlet opening () and to an outlet opening () in a communicating manner. The bottom () is made permeable for airborne sound and connects the two ducts () to one another in an airborne sound-transmitting manner.
