筒。In the multiple exhaust pipe of an internal combustion engine, the inner pipe of the exhaust pipe is formed of a ceramic material and the outer pipe of the exhaust pipe is formed of a metal material, and a heat insulating layer consisting of an air layer is formed between the inner and outer pipes. An annular elastic member is disposed between the inner pipe and the outer pipe to support the inner pipe, and an annular protrusion is formed along the outer peripheral wall of the inner pipe to block air convection within the heat insulating layer. A distinctive feature of the internal combustion engine is its multiple exhaust stacks.
