1. An exhaust gas routing component for an exhaust gas system of an internal combustion engine, the exhaust gas routing component comprising:
a tube-like component body defining a longitudinal axis (L);
said tube-like component body having a first component body end region and a second component body end region;
said second component body end region being arranged in the direction of said longitudinal axis (L) at a distance from said first component body end region;
said component body including a tube-like outer body and a tube-like inner body accommodated in said tube-like outer body;
said inner body being fixed in a fastening region to said outer body;
a sliding guide acting between said outer body and said inner body;
said sliding guide being configured to permit a relative movement of said inner body relative to said outer body outside of said fastening region;
wherein:
said outer body defines an inner space; and,
said sliding guide comprises:
a guide recess extending in the direction of said longitudinal axis (L), and with reference to said longitudinal axis (L), opening radially inwardly to said inner space of said outer body; and,
