Muffler is one of the important devices in the exhaust system. This plays a key role in reducing the exhaust gas noise and pressure, before when they are expelled from the exhaust system. This noise comes from the exhaust manifold which is due to the large pressure in the difference between atmosphere and exhaust gases. For quite operation Muffler is used. In this paper, a muffler with selective sound-absorbing material like carbon fiber and rockwool was used. Two different mufflers (original and modified) are designed and modelled Creo2.0. Acoustic—structural simulation is done for the two different models of muffler along with two assigned sound-absorbing materials. The simulation results are explained that the acoustic power level (dB) and frequencies are reduced for the modified model than the original model when the Rockwool material is used.
