In severe cases, it will also lead to engine failure. In summer, due to the high exhaust gas temperature, the external ambient temperature will rise after discharge, so that the city temperature will continue to rise. This noise reduction exhaust component can heat the exhaust pipe in winter. Cooling the exhaust pipe in summer reduces the failure probability of the engine and the exhaust pipe, and improves the urban living environment.
