Abstract: An exhaust muffler with a tail pipe for suppressing ripples, increasing an engine output and improving fuel consumption efficiency is provided. A chamber is provided in the middle of an exhaust pipe for an internal combustion engine. A tail pipe connected to an end portion of an exhaust opening of the exhaust pipe is provided. A plurality of fins are disposed inside the tail pipe in a spiral shape that is gradually widened toward a discharging direction of the exhaust gas. The chamber includes a cover body and an internal exhaust pipe surrounded by the cover body. The internal exhaust pipe includes a diffusion exhaust pipe having a wide bore and a compression exhaust pipe having a narrow bore. Diffusion pores are drilled on a portion of the side surface of the internal exhaust pipe.
