Weak pressure waves similar to blast waves are generated in an exhaust pipe of engines of a car during running at high speed. When the waves emitted from the end of the exhaust pipe, a jarring noise is generated. To diminish such the noise effectively, a sub-silencer is installed in front of a main-silencer in the exhaust pipe. In the present study, four types of expansion region were investigated by measuring the pressure decay in the test section. A two-stage expansion model was the most effective to decrease the peak over pressure of the blast waves.
