ABSTRACT:
An exhaust muffler for competition car engines has a cylindrical, outer or main shell with an inlet at one end smaller than or the same diameter as the main shell and with an outlet at the other end smaller in diameter than the main shell. Inside the main shell is a series of separate, spiral baffles all having the same depth or axial dimension of the spiral and placed equidistantly from each other. The spiral baffles are attached to the interior of the main shell by welds. A round tube open at both ends passes through the center of the spiral baffles beginning at the inlet of the main shell and ending at the outlet of the main shell.
