PURPOSE: An exhaust system is provided to delay the deterioration of the purification rate of an oxidation catalyst by maintaining an optimally set traveling distance for a set time. CONSTITUTION: An exhaust system comprises an exhaust line, an oxidation catalyst, and a controller. Exhaust gas discharged from an engine passes through the exhaust line. The oxidation catalyst is installed in the exhaust line and purifies harmful materials in the exhaust gas. The controller senses the traveling distance of a vehicle and maintains the temperature of the oxidation catalyst for a set time based on the cycle of the traveling distance.
