Our final target of this study is developing a simulation package for predicting the pressure pulsation inside pipe-system and its sound pressure near the end of automotive exhaust system. This paper reports on the modeling of each components of real automotive exhaust system under the air pulsation by air-blower is working in laboratory. Three kinds of fundamental element model in the characteristic method are considered to construct the models of each component. The comparison of pressure measured and calculated is carried out to improve the models both static and dynamic conditions.
