    The invention discloses an automobile exhaust silencer assembly with an improved structure. The automobile exhaust silencer assembly comprises an automobile exhaust silencer main body, one end of theautomobile exhaust silencer main body is connected with an air inlet pipe, and the other end of the automobile exhaust silencer main body is connected with an exhaust pipe. The automobile exhaust silencer main body comprises a shell, a groove is formed in the shell, a matched anti-collision sleeve is arranged in the groove, and an extending part is arranged on the anti-collision sleeve. The extending part at one end extends to the exhaust pipe and surrounds the exhaust pipe, and the extending part at the other end extends to the air inlet pipe and surrounds the air inlet pipe. The air inlet pipe and the exhaust pipe are each provided with a plurality of connecting holes, the connecting holes are sealed through sealing layers, and elastic filter nets are fixed in the sealing layers. The airinlet pipe and the exhaust pipe are not easy to be blocked and damaged. The anti-collision effect of the automobile exhaust silencer main body is better, and the surface is not easy to be damaged. The interior of the exhaust pipe and the interior of the air inlet pipe are not easy to be affected with damp and damaged.
