PURPOSE: A performance and a durability experiment device of an engine exhaust system is provided to make an optimal design of the engine exhaust system by testing whether the engine exhaust system is optimally designed before applying to an actual power system. CONSTITUTION: A performance and a durability experiment device of an engine exhaust system comprises a fuel supply line (110), an air supply line (120), a combustion chamber (130), an exhaust pipe, an experiment condition means, a control unit (150), and a measure unit (160). The fuel supply line guides a fuel pumped from a fuel pump (112) through a pipe. The air supply line guides an air in an air pump (124) through the pipe. The combustion chamber generates a flame through an ignition by mixing the fuel and the air. The combustion chamber comprises an air inlet in one end side. The exhaust pipe discharges an exhaust gas ejected from the combustion chamber. The experiment condition means is mounted to experiment based on conditions by operating an engine exhaust system (102) by using an exhaust gas. The control unit reproduces identically circumstances generated according to a change of an engine operation condition reproducing circumstances generated according to an actual engine operation condition change. The measure unit records by measuring an experimental result of the engine exhaust system according to the engine operation condition.
