Claims

[Scope of utility model registration request]

An air guide pipe is connected to the end of the exhaust pipe at the end of the exhaust system of the engine, and the air guide pipe runs from the air inlet opening toward the front to the air outlet opening toward the rear on both sides of the exhaust pipe. The inner surfaces of the left and right sides of the exhaust pipe are oppositely provided with guide walls that are narrowest near the opening end of the exhaust pipe, and the pressure near the opening end of the exhaust pipe is reduced by the air flow flowing in from the air inlet, thereby exhausting the exhaust pipe. An engine exhaust system characterized by reducing system back pressure.
