PURPOSE: An exhaust flue of automotive vehicle utilizing airflow is provided to accomplish an improved exhaust performance and energy efficiency of engine, and improved durability of parts. CONSTITUTION: An exhaust flue comprises a streamline-shaped outer surface for leading an airflow to form a lower pressure area where an air pressure is partially reduced, a cavity at an inside thereof, an exhaust pipe(1) connected thereto for supply of exhaust gas from a vehicle into the cavity, and a body(10) having one or more outlet slit(10a) at the outer surface adjacent to the lower pressure area for allowing the exhaust gas to be discharged to the lower pressure area, thus permitting a smooth exhaust of combustion gas utilizing an airflow naturally generated during an operation of vehicle without additional driving device.
