The invention relates to the technical field of automobile exhaust, and discloses an automobile exhaust device which comprises an exhaust protection structure, a lower flow guide mechanism is arranged at one end of the exhaust protection structure, a pump flow anti-immersion mechanism is installed in the exhaust protection structure, and an upper edge constant pressure mechanism is installed on the surface of the exhaust protection structure. A heat dissipation supporting mechanism is arranged at the top of the exhaust protection structure, and a flow guide soft connection mechanism is arranged at one end of the heat dissipation supporting mechanism. According to the automobile exhaust device, through the arrangement of the exhaust protection structure, the lower flow guide mechanism, the pump flow anti-immersion mechanism, the upper edge constant pressure mechanism, the heat dissipation supporting mechanism and the flow guide soft connection mechanism, automobile exhaust can be accelerated and pressurized through the pump flow anti-immersion mechanism when an automobile wades into water, and the exhaust emission capacity is improved; and meanwhile, the rotating flow pushing spiral fan continuously pushes outwards to actively drain water, so that water flow is prevented from entering the silencer.
