The invention relates to an exhaust gas line arrangement (100) for an internal combustion engine, comprising an exhaust gas line (110) extending substantially along a longitudinal axis (101) and designed to at least partially guide exhaust gas of the internal combustion engine; an opening (130) provided in the exhaust gas line (110) arranged substantially radially in relation to the longitudinal axis (101); a shielding housing (140) which is attached to the exhaust gas line (110) from the outside in such a way that it substantially entirely surrounds the opening (130); and a waveguide (150) which is coupled to the shielding housing (140) and/or the exhaust gas line (110), and designed to couple electromagnetic waves into the shielding housing (140) in such a way that the electromagnetic waves are propagated through the opening (130) into the exhaust gas line (110).
