PURPOSE: Flexible pipe structure for dual exhaust pipes is provided to effectively absorb transmission of exhaust vibration of an engine to an exhaust system, improve the engine output through reduction of exhaust pressure and increase of volumetric efficiency, and improve layout of the exhaust system and durability of a bellows. CONSTITUTION: In dual exhaust pipes, first and second exhaust pipes are connected to exhaust ends of a V-shaped engine and the exhaust pipes are extended to the rear end and are joined. Flexible pipe structure for the dual exhaust pipes comprises a pair of dual flanges(12) having two combining holes(13,14) to connect the first and second exhaust pipes; first and second bellows(15,16) combined between the dual flanges, to independently interconnect the first and second exhaust pipes; and an outer blade combined between the dual flanges. The outer blade covers the outside of the bellows.
