A pipe length adjusting type muffler is provided to extend the path of a pipe to discharge exhaust gas and reduce an exhaust booming noise. An exhaust pipe has the first end connected to an exhaust manifold and the second end extending in a longitudinal direction to convey an exhaust gas. A resonator includes an inflow pipe(210), a return pipe(220), an exhaust pipe(230), and a coupling member(240). The inflow pipe has the first end coupled to the exhaust pipe such that the exhaust gas is intruded. The inflow pipe has the second end extending in a straight line. A return pipe communicates with the second end of the inflow pipe. The return pipe winds around the outer circumference surface of the inflow pipe such that the exhaust gas turns round the outside of the inflow pipe. The exhaust pipe is connected to the return pipe. The exhaust pipe faces to the inflow pipe to discharge the exhaust gas. The coupling member couples the return pipe to the inflow pipe. A tale pipe is connected to the exhaust pipe to discharge the exhaust gas to the outside of a vehicle.
