[0042] Specifically, when the automobile engine muffler with exhaust function is in use: the automobile exhaust gas enters the interior of the pipe body 1 through the intake pipe 201, and the exhaust gas will move from the dispersion groove 203 and the extension pipe 204 respectively. The gas enters the interior of the pipe body 1 through the dispersion groove 203, and is then guided by the two guide rings 10, and then discharged through the exhaust pipe 206. At the same time, the gas that has not passed through the dispersion groove 203 will pass through the extension pipe 204. At this time, the silencer cotton 205 will absorb part of the noise. When the gas is separated by the dispersion groove 203, the moving path of the dispersion groove 203 will be increased, thereby attenuating the noise and greatly improving the silencing effect. Then, the protective cylinder 301 is inserted into the outside of the pipe body 1, so that one end of the protective cylinder 301 is in contact with the limiting ring 6, and then the protective cylinder 301 is fixed by the bolt 7. When the automobile moves, the protective cylinder 301 can prevent external stones from contacting the pipe body 1 and causing damage to the pipe body 1, thereby improving the service life of the pipe body 1.
