Exhaust gas routing component for an exhaust gas system of an internal combustion engine

An exhaust gas system of an internal combustion engine, the exhaust gas system comprising:

• a first tube-like exhaust gas routing component;
• a second tube-like exhaust gas routing component;
• a third tube-like exhaust gas routing component interconnecting said first and second tube-like exhaust gas routing components;
• and,
• said third tube-like exhaust gas routing component including:
• 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,
• on said inner body in assignment to said guide recess, a guide projection extending in the direction of said longitudinal axis (L) and engaging, in relation to said longitudinal axis (L), radially outwardly into said guide recess assigned thereto.
