The invention discloses an exhaust pipe capable of improving the efficiency of an exhaust system, and relates to the field of exhaust pipes, the exhaust pipe comprises an exhaust main pipe, and the end part of the exhaust main pipe is communicated with a first exhaust auxiliary pipe and a second exhaust auxiliary pipe which are bifurcated; the inner wall of the second auxiliary exhaust pipe is provided with a low-pressure suction area for draining and discharging gas at the gas outlet of the main exhaust pipe to the second gas outlet, and when the gas discharged from the main exhaust pipe is conveyed into the first auxiliary exhaust pipe and the second auxiliary exhaust pipe, part of the gas enters the first auxiliary exhaust pipe to be discharged; a low-pressure suction area is arranged on the inner wall of the lower end of the second auxiliary exhaust pipe, and the gas at the gas outlet of the main exhaust pipe can be sucked into the second auxiliary exhaust pipe, so that the phenomenon that a large amount of gas enters the first auxiliary exhaust pipe is avoided; and the low-pressure suction area has the effect of reducing the weakness degree when the gas is conveyed.
