The present invention discloses an improved structure of a muffler at the rear end of an exhaust pipe, mainly comprising a tapered inner pipe inside a tapered conical outer pipe, and a plurality of silencing holes being disposed on the wall of the inner pipe, and a silencing cotton wrappers around and covers the external rim of the inner pipe, and a sleeve being disposed in the inner pipe proximate to the rear end of the inner pipe. The front end of such sleeve is a tapered conical pipe, and the rear end slight extends to the outside of the rear end of the external pipe. A decorative lid covers the rear end surface of the external pipe, and a gas-receiving pipe having a French connector being soldered to the front end of the external pipe, and an n-shaped fixing bracket having a fixing hole on it being soldered to an appropriate position on the external surface of the external pipe proximate to the rear end. The assembly of the foregoing components enables the muffler to increase the output torque of the engine, reduce the noise, and provides an easy installation for all sorts of vehicles.
