PURPOSE: A post-processing system of exhaust gases, capable of decreasing fuel consumptions and a decline in outputs because the exhaust gas selectively passes through a GPF(Gasoline Particulate Filter) according to an operating condition of an exhaust gas engine. CONSTITUTION: A post-processing system of exhaust gases comprises a exhaust line(110), a GPF(Gasoline Particulate Filter)(130), a bypass line(140), and a controller(160). The exhaust gas discharged from an engine(100) passes through the exhaust line. The GPF is installed in the exhaust line and filters harmful materials in the exhaust gas. The bypass line is installed in the exhaust line and the exhaust gas is bypassed through the by pass line. The controller senses a driving condition of the engine and passes the exhaust gas through the GPF. The controller passes the exhaust gas to the bypass line.
