A catalytic converter is an essential emissions control part and is a key component inspected during a Smog Check. It contains rare metals responsible for converting smog-causing pollutants that pass through a vehicle’s exhaust system into less harmful compounds. Because these metals have a high recycle value, catalytic converter theft has become increasingly common.
Experienced thieves can remove a catalytic converter in one to two minutes using basic tools. What can net a thief hundreds of dollars at a scrapyard or recycler can then cost you thousands of dollars to replace, depending on the make and model of your vehicle. Learn more below on how you can protect your catalytic converter and prepare for your vehicle’s next Smog Check.
WARNING SIGNS OF A BAD CATALYTIC CONVERTER
If your vehicle has any of these warning signs, then your old catalytic converter may need to be replaced.
-
- Check engine light: If you have a 1996-or-newer (OBDII) vehicle, a check engine light may indicate a problem with your catalytic converter. A diagnostic scan tool plugged into the OBDII port under the dash may show a P0420 or P0430 code.
- Sulfur smell: If you smell rotten eggs when your vehicle is running, then the catalytic converter may not be catalyzing the sulfur in the exhaust gas.
- Emissions test failure
- Exterior discoloration
- Sluggish acceleration
- Decreased fuel economy
- Hard-start/no-start engine condition
AT-HOME DIAGNOSIS
If any of the warning signs are present, then two at-home tests may help identify a bad catalytic converter. If you don’t have the tools or the inclination, then an auto repair/muffler shop, dealer or mechanic can perform these tests for you.
-
- Exhaust temperature: Once the engine is up to normal operating temperature, measure the exhaust temperature directly, before and after the converter, using an infrared thermometer. If there is a big difference (at least 100 degrees), then the converter may need to be replaced. A large temperature difference can result from a clogged converter that traps exhaust gasses and makes it less efficient.
-
- Engine vacuum: If there is no check engine light on or your vehicle was built before 1996 (pre-OBDII), then an engine vacuum test may be necessary if there are other warning signs. When the engine is idling, hook up a vacuum gauge to the intake manifold and record the reading. Then, rev the engine to 2,500 RPM (a helper will make this easier) and observe the measurement again. If the gauge doesn’t return to a similar reading as it showed when idling, or it is very slow to do so, the converter could be faulty.

How can I protect my vehicle from catalytic converter theft?
- Install a theft prevention device on your catalytic converter – A licensed auto shop can install a protective plate, shield, clamp, cage, strap, or other device to secure your catalytic converter. The device must be properly installed to avoid any damage to the catalytic converter and ensure all identifying information is visible.
- Mark your catalytic converter – Engraving or etching your catalytic converter with your vehicle identification number (VIN) or license plate number may deter theft. It may also alert a reputable scrap dealer that the device is stolen and can help to identify the owner. If you choose to also have your catalytic converter painted with bright, fluorescent paint, be sure that the paint does not cover any identifying information. Check with your local law enforcement agency for information on any upcoming no-cost engraving/etching events.
- Adjust your vehicle’s alarm – A well-calibrated alarm can detect vibration and alert you or scare thieves away.
- Park your vehicle in a safe location – If you have a garage, use it. Consider installing motion-sensitive lights if you park in your driveway. Park close to a building entrance or in a well-lit and high-traffic area when parking in a public lot.

FEDERAL VS. CARB
California car? California certified emissions vehicle? No matter how you say it, this phrase means different things to different people. For those of you in the repair field or looking to get the correct converter for your vehicle, it has come to define our world.
Making the distinction between the two is hardly new. The line was drawn back in the late 60’s, but its significance has grown over the last few years. On January 1, 2009, California (CA) adopted and put into place, new laws regarding the manufacture, sale and installation of aftermarket catalytic converters. Since then, New York (NY) and Maine (ME) have adopted those same laws.
Selecting the Right Converter
This article is not about the laws themselves, but rather one area of the law that seems to be the most confusing to those who may not fully understand the difference. That is the process of selecting the proper converter for an individual vehicle. Although the letter of the law in NY and ME is not exactly as it is in CA, the principle is the same. If an OBD II vehicle is built to meet CARB standards, then it requires a CA certified converter. For example, one significant difference is that NY will allow EPA (Federal) certified vehicles to use a non-CARB part whereas CA does not make that distinction.
The most important takeaway is to recognize that a vehicle meeting the stricter CA standards from the factory has a catalytic converter, as well as other emission components on it, that is designed to meet those tougher standards. Therefore it is important to maintain the integrity of the system. In order to do that, you have to know what emission standard the vehicle is designed to meet and what components make up that system.
So how does a technician, retail counter person or vehicle owner retrieve this information? It can be found on the Vehicle Emission Control Information (VECI) label located in the engine compartment. Typically it will be located on the strut tower, radiator support, or on the underside of the hood. This label contains information about the emissions systems and components of that specific vehicle along with a statement referring to the standards to which that vehicle conforms. Refer to this information to help choose the proper catalytic converter for the vehicle.
CA Approved Catalytic Converter
Catalytic Converters are emission control devices that are designed to last the life of the vehicle, do not normally require replacement without cause. A check engine light for catalytic efficiency does not by itself condemn a catalytic converter. There could be another reason or even more parts that have failed and do not necessarily require a catalytic converter replacement. Hence per example an oxygen sensor not functioning correctly. Your vehicle should be diagnosed properly before a catalytic converter is to be replaced. If you would like to schedule an appointment for a complete diagnosis click here.
My car has a PO420! Does that mean my converter is bad?
NO. The P0420 code, by definition reads “bank one Catalyst Efficiency low” as a result most people will just replace the converter. A vehicle displaying this code is indicating that something is causing the converter to operate out of specification. Furthermore, a diagnostic and certainly an inspection are required before condemning any parts as “bad” or defective.
While you still may need a catalytic converter. FMS can perform a Catalytic Converter Pre-Test. The inspection is free with the purchase of needed components to correct the issue. Please make an appointment to drop the vehicle off for the complete inspection.
How can I determine my cars emissions certification levels?
All vehicles will come with a VECI (Vehicle Emission Control Information) label located in the engine compartment.
With optimized exhaust flow, your engine requires less energy to expel gases, leading to better fuel economy under certain driving conditions. This makes performance exhaust systems an eco-friendly upgrade, reducing the strain on both your wallet and the environment.
How do I know that the catalytic converter I purchase is (CARB) California Air Resource Board approved?
You can check with CARB on the approval for your car or truck by contacting the Helpline at 1-800-242-4450. You may also contact FMS for a quote or another opinion. Finally you may click this link to select your search https://ssl.arb.ca.gov/AftermarketParts/catalysts
What is the Warranty on a Replacement CA Approved Catalytic Converter?
Federal EPA regulates a 2 year or 25,000 mile guarantee
California CARB regulates a 5 year or 50,000 mile guarantee
Factory replacement converters from the dealer have a warranty for 1 year or 12,000 miles. Most noteworthy is cars have a 8 year 80,000 mile warranty on the OE converter the vehicle came with. If your car is within the 8/80 certainly call your dealership with your VIN number so they may assist you with the warranty information.
Can I use a catalytic converter cleaner on my car?
Yes, we suggest Cataclean by Mr Gasket. Cataclean contains solvents that can break down deposits formed by oxidation and polymerization of hydrocarbon in fuel delivery systems. Cataclean also includes acetone which is known to improve the efficiency of fuel combustion. Acetone has been used in race cars to enhance octane rating and make fuel burn more evenly and completely. When Cataclean combusts, carboxylic acids, aldehydes and active peroxy compounds are formed. These compounds in the exhaust vapors work to clean the surfaces inside the converter. The result is the removal of deposits from the surface of the core, which increases the catalyst’s ability to remove harmful exhaust emissions such as, carbon monoxide & nitrogen oxides.
