ABSTRACT OF THE DISCLOUSURE: A muffler for automobile internal combustion engines consisting briefly of a housing having an inlet end where the exhaust gases are channeled through a tubular member having a helical member so that the gases are forced into a spiral flow pattern. The helical member extends beyond the end of the tubular member so that the gases are then permitted to follow a larger spiral pattern where they reflect against the walls of the housing. The housing has an outlet opening which is smaller than the housing diameter which causes compression of the gases and further reflection and interference of the sound waves. The muffler is formed with a counterflow reverberation chamber, a central chamber and a directional- flow reverberation chamber.
