Zusammenfassung:	To provide an exhaust system having excellent exhaust emission control performance.SOLUTION: An exhaust system 1 includes: an exhaust pipe 2 for discharging exhaust gas discharged from an engine 101; a plasma reactor 3 interposed in the middle of the exhaust pipe 2 and adsorbing and decomposing hydrocarbon (HC) included in the exhaust gas; and an HC storage device 4 interposed on the upstream side of the plasma reactor 3 in the exhaust pipe 2 and adsorbing and emitting hydrocarbon (HC). The plasma reactor 3 includes first zeolite that adsorbs hydrocarbon (HC), and the HC storage device 4 includes second zeolite that adsorbs hydrocarbon (HC). Either one of the first zeolite or the second zeolite contains metal.SELECTED DRAWING: Figure 1 【課題】優れた排ガス浄化性能を有する排気システムを提供すること。【解決手段】排気システム１が、エンジン１０１から排出される排ガスを排気するための排気管２と、排気管２の途中に介在され、排ガスに含まれる炭化水素（ＨＣ）を吸着し、分解させるプラズマリアクター３と、排気管２のプラズマリアクター３の上流側に介在され、炭化水素（ＨＣ）を吸着および放出するＨＣ貯留装置４とを備え、プラズマリアクター３は、炭化水素（ＨＣ）を吸着する第１ゼオライトを備え、ＨＣ貯留装置４は、炭化水素（ＨＣ）を吸着する第２ゼオライトを備え、第１ゼオライトまたは第２ゼオライトのいずれか一方が、金属を含有する。【選択図】図１
