Are vehicles manufactured after 1984 required to have a catalytic converter?

Vehicles manufactured after 1984 are indeed required to have a catalytic converter. This is because the United States government implemented regulations to control emissions and reduce pollution, mandating that all new vehicles produced after this date must be equipped with catalytic converters. These devices play a critical role in converting harmful exhaust gases into less harmful emissions before they exit the vehicle.

Although there may be various types of exemptions or additional considerations for certain vehicles or conditions, the general requirement for most passenger vehicles manufactured after 1984 to have a catalytic converter remains solid. This requirement has been a major factor in helping to meet environmental standards set forth by legislation such as the Clean Air Act, aimed at improving air quality and protecting public health.
