The numerical study of a compressible flow in a closed coupled catalytic converter system was performed to understand the flow characteristics and to improve the flow distribution of exhaust gases. For steady flow analysis, the effects of geometric factors(junction, mixing pipe, cell shape etc.) on flow characteristic and distribution in substrate are mainly investigated. Unsteady flow analysis shows that there are severe interferences of each pulsating exhaust gas flow that influence greatly on the flow uniformity.<br/>
