An improved muffler diffuser insert adapted to be used with, and mounted within, an exhaust muffler for effectively helping to reduce noise and back pressure attendant to engine operation. The diffuser comprises a cap end for abutting against an exhaust end of the muffler when the muffler diffuser is mounted within the muffler, which has at least one exhaust opening defined therein for cooperation with the exhaust end of the muffler so as to permit an exhaust flow from the exhaust end of the muffler to pass through. A body portion is connected to the cap end, and defines therein an elongated opening for permitting the exhaust flow from the muffler to pass through. A distal end of the body portion comprises an outermost end and two sound deflection portions positioned on either side of the outermost end for use in deflecting sound waves contained in the exhaust flow so as to enhance noise diffusion.
