What Is a Catalytic Converter?

Automakers use a catalytic converter to reduce tailpipe emissions to comply with the Clean Air Act of 1970. This component uses chemical processes to convert harmful pollutants into less harmful emissions.

There are many types of catalytic converters to choose from. This includes:

A pair of exhaust pipes with two different types.

Direct-Fit Catalytic Converter

This type of catalytic converter has fittings on each end that allow them to be fitted or bolted directly into the vehicle. Because they are designed to the exact specifications of the vehicle, they tend to be more expensive than universal converters and have the following features:

  • Little to no exhaust fabrication is required
  • Easy to install
  • Bolt-on design
  • Vehicle specific

Universal Catalytic Converter

These converters can be installed in almost any vehicle as long as the diameters of the inlet and outlet tubes are the same on the converter and the exhaust system. While it is more affordable than direct-fit converters, it requires professional installation.

Manifold Catalytic Converter

Like direct-fit converters, this catalytic converter bolts directly into a vehicle’s exhaust line. They are integrated into a vehicle’s exhaust manifold, a component that collects exhaust gases from multiple cylinders into a single pipe.

Manifold catalytic converters feature a specialized design and fitment and require professional installation or advanced mechanical knowledge.

CARB-Compliant Catalytic Converters

The California Air Resources Board (CARB) has its own environmental regulations that CARB-compliant converters must meet. This is essential if you want your vehicle to be registered in California.

Federal/EPA-Compliant Catalytic Converters

If your vehicle is registered and operated outside of California, there are two Federal/EPA-compliant converters to choose from:

Heavy Metal Catalytic Converters

Suitable for non-California (49-state) vehicles, these converters are Environmental Protection Agency (EPA), but not CARB.

OEM-Grade Catalytic Converters

These converters meet both EPA and CARB standards. However, only CARB-approved converters can be used if a vehicle is registered in California.
