No, a licensed dealer cannot legally sell you a car without a catalytic converter as a functioning, road-ready vehicle. The catalytic converter is a critical emissions control device required by the Clean Air Act, a federal law enforced by the Environmental Protection Agency (EPA). Selling a vehicle without one for on-road use would violate federal regulations. The only exceptions are if the car is explicitly sold "for parts" or "for off-road use only," which must be clearly stated in the bill of sale and title. Buying such a car comes with significant risks, including the inability to register it or pass your state's emissions inspection.
The primary reason is compliance with emissions standards. Since 1975, all gasoline-powered vehicles sold in the U.S. must be equipped with a catalytic converter to reduce harmful pollutants like hydrocarbons, carbon monoxide, and nitrogen oxides. A dealer selling a car without one is effectively distributing a vehicle that does not meet the minimum federal environmental standards it was certified to meet.
If you encounter a dealer offering a car without a catalytic converter, it's a major red flag. It suggests the vehicle may have been poorly repaired after theft or damage, or the dealer is operating unethically. Before purchasing any used car, especially from a private party, it's wise to have a pre-purchase inspection by an independent mechanic. They will check for the presence and condition of the catalytic converter and other essential components. Driving without a catalytic converter is illegal in all 50 states for on-road vehicles, and penalties can include substantial fines.
