An exhaust gas duct for a row of cylinders of an internal combustion engine is so constructed that corrosion, especially fretting corrosion, is minimized by mounting the exhaust gas pipe section in a cooling housing so that contact between the pipe section and the cooling housing is limited to the end portions of the exhaust gas pipe section, thereby leaving an uninterrupted gap between the pipe section and the housing all along the pipe section. The end mountings permit an axial movement, and, if desired, also a radial movement of the pipe section relative to the liquid cooled housing for compensating thermal expansions and contractions. The end mountings are easily accessible for inspection and additionally, permit an easy assembly and disassembly of the components.
