PURPOSE: An exhaust muffler for a V6 engine using flexible fuel is provided to reduce noise by using the flexible fuel and to reduce a producing cost and weight by simplifying structure. CONSTITUTION: An exhaust muffler for a V6 engine with flexible fuel comprises an exhaust muffler(1) dropping temperature and pressure by diffusing exhaust gas; a cylinder case(2) divided into front, middle and rear chambers(7,8,9); front and rear wall members(3,4); an inlet pipe(5) penetrating the wall members from a front face(10) of the cylinder case; an opened portion(5a) of the inlet pipe interlocked with the rear chamber; an exhaust pipe connected to an exhaust manifold; an outlet pipe(6) penetrating the wall members from a rear face(11) of the cylinder case; a front opened portion(6a) of the outlet pipe interlocked with the front chamber; plural holes(12) penetrated on the inlet pipe and the outlet pipe; and a protecting pipe(14) isolating the holes of the outlet pipe by penetrating the rear wall member. Thereby, the exhaust muffler for the V6 engine reduces noise by using the flexible fuel.
