Is your vehicle’s catalytic converter acting up? A crucial part of the emissions control system, the catalytic converter breaks down unburned fuel and toxic substances in the exhaust gases from the engine. If the converter develops an issue and stops working correctly, your vehicle will fail its next emissions test, leading to fines and other legal problems.
You need to get a replacement catalytic converter and install it in your vehicle before returning to the road. There are many products on the market. Fortunately, we can recommend catalytic converters with the excellent performance and reliability you deserve.
Types of Catalytic Converters
There are several different types of catalytic converters. Whether you need to replace a faulty converter or want to upgrade to a high-performance part, you must select one that’s the same type. An otherwise excellent catalytic converter might not fit under your vehicle or prove incompatible with the attachment points.
By Fit
Direct-Fit Catalytic Converter
Direct-fit catalytic converters bolt directly into the exhaust line. They’re relatively easy to replace and install in your vehicle.

Manifold Catalytic Converter
Manifold converters get their name from the way they bolt onto the exhaust manifold. They take exhaust gases from several cylinders and direct them into a single exhaust pipe.
Manifold converters are designed for use in certain vehicle models. You cannot install them in other models that aren’t compatible. Also, they generally cost more than direct-fit and universal catalytic converters. And because manifold converters are built into the exhaust manifold, you must replace the entire manifold if it fails.

Front Manifold Converter and Rear Catalytic Converter Kit
This type has two different catalytic converters. It has a manifold converter up front and a catalytic converter in the back. Together, the two parts deal with NOx and other pollutants in exhaust gas.

Universal Catalytic Converter
Universal catalytic converters are compatible with most vehicles. As long as the diameters of the converter’s inlet and outlet tubes match their counterparts on the exhaust system, the part can bolt onto your car or truck with no risk of leaks caused by a loose connection.
Some universal catalytic converters might need additional work during installation. Check the product packaging or the manual to see if the cat con needs cutting, welding, or other work.
You also must ensure that the catalytic converter meets the emission standards of the state where you will register your vehicle. Otherwise, you cannot legally drive it.

By Emissions Standard
Most catalytic converters are designed to comply with one of two emission standards. One is the federal EPA standard; the other is the CARB standard. It’s important to know the emissions standard of your current cat con and pick a replacement that shares the same performance.
Federal EPA Standard Compliant
The Environmental Protection Agency (EPA) is the federal government agency that protects the environment and human health. The EPA sets guidelines for how much pollutants are allowed in a vehicle’s emissions.
Many catalytic converters follow the federal EPA standard. They’re road-legal in 46 states that adhere to the federal minimum levels of NOx and other pollutants in vehicle emissions.
Some states implement stricter emission standards than those set by the EPA. These are California, Colorado, New York, and Maine. You cannot ship a catalytic converter that doesn’t meet their regulations to those states. Furthermore, you cannot install them in vehicles that were originally bought in those states.

CARB and Federal EPA Standards Compliant
The California Air Resources Board (CARB) is a state government agency that works to reduce air pollution in California. One of its jobs is setting standards for vehicle emission control parts like the catalytic converter.
CARB emission standards are more stringent than the federal EPA standard. That means a CARB-compliant catalytic converter is legal in all 50 states. If you expect to drive in California, Colorado, New York, or Maine, get a converter that meets CARB standards.
