摘要：
An exhaust muffler with a tail pipe for suppressing ripples, increasing an engine output and improving fuel consumption efficiency is provided. A chamber 10 is provided in the middle of an exhaust pipe 1 for an internal combustion engine. A tail pipe 20 connected to an end portion of an exhaust opening of the exhaust pipe 1 is provided. A plurality of fins 21 are disposed inside the tail pipe 20 in a spiral shape that is gradually widened toward a discharging direction of the exhaust gas. The chamber 10 includes a cover body 11 and an internal exhaust pipe 12 surrounded by the cover body 11. The internal exhaust pipe 12 includes a diffusion exhaust pipe 13 having a wide bore and a compression exhaust pipe 14 having a narrow bore. Diffusion pores 15 are drilled on a portion of the side surface of the internal exhaust pipe 12.
