Abstract

An exhaust gas routing component for an exhaust system of an internal combustion engine comprises a tubular component body (14) with a first component body end region (16) and a second component body end region (20) arranged in the direction of a component body longitudinal axis (L) at a distance from the first component body end region (16), wherein the component body (14) comprises a tubular outer body (24) and a tubular inner body (26) received in the tubular outer body (24), wherein the inner body (26) is fixed in a fastening area (98) on the outer body, and wherein a sliding guide (96) is provided acting between the outer body and the inner body (26), allowing a relative movement of the inner body (24) with respect to the outer body (24) outside the fastening area (98).
