An automobile exhaust silencing system comprises a silencer front air inlet pipe assembly, an exhaust brake valve assembly, a silencer rear air inlet pipe assembly and a postprocessor assembly which are sequentially connected, the silencer front air inlet pipe assembly, the exhaust brake valve assembly and the silencer rear air inlet pipe assembly are all arranged on the outer side of a right longitudinal beam, and the postprocessor assembly is located below a front cross beam. The silencer front air inlet pipe assembly is connected with an engine exhaust manifold, the upper portion of the silencer front air inlet pipe assembly is installed on the ventral face of the right longitudinal beam through an upper support assembly, and the lower portion of the silencer front air inlet pipe assembly is installed on the ventral face of the right longitudinal beam through a lower support assembly. The postprocessor assembly is fixed to the lower wing face of the front cross beam through the left hanging assembly, and the postprocessor assembly is fixed to the lower wing face of the right longitudinal beam through the right hanging assembly. The design is simple and convenient to arrange and good in shock absorption and noise reduction effect.
