An exhaust gas routing component for an exhaust gas system of an internal combustion engine includes a tube-like component body with a first component body end region and a second component body end region arranged in the direction of a component body longitudinal axis at a distance from the first component body end region. The component body includes a tube-like outer body and a tube-like inner body received in the tube-like outer body. The inner body is fixed in a fastening region on the outer body. A sliding guide is provided which acts between the outer body and the inner body and permits a relative movement of the inner body in relation to the outer body outside the fastening region.

A process manufactures an exhaust gas treatment device including a tubular circumferential wall () elongated along a longitudinal axis (L) with two axial end areas, an exhaust gas treatment unit () arranged in the circumferential wall and a closing element () connected to the circumferential wall at the two axial end areas. The exhaust gas treatment unit is held at the circumferential wall by a supporting material layer () enclosing the exhaust gas treatment unit and supporting same in relation to the circumferential wall. The process includes arranging a first of the two closing elements at one of the axial end areas of the circumferential wall, pushing the exhaust gas treatment unit enclosed by the supporting material layer into the circumferential wall from the other axial end area (), and arranging a second of the closing elements at the other axial end area of the circumferential wall.
