I live in California and have been told I need an OBD-II catalytic converter for my car? Will your converters work?
California has special emission laws, which prohibit the use of aftermarket catalytic converters on 1996 and newer model year vehicles unless the converter in question has been approved for your car. So from a standpoint of whether our converters will work on your car or not, yes, they will probably work, but no, we cannot legally sell them to you unless the State of California has approved the part for your car. Please contact us with specific details about your car through our direct fit parts request form. and we will let you know whether we have any parts for your particular vehicle.

I live outside California but I have a California emissions vehicle. Will your converters work on my vehicle?
So long as the correct unit for your application is used, the answer is yes. Our parts are engineered to work correctly on the applications they are intended for. The parts listed in our online catalog work on the applications listed, including California emission vehicles located outside the state of California.

I have a California emissions vehicle. I have been told that I need a California converter. Is this true?
If you live in the state of California, you do need California legal converters, so this statement is true. If you live outside the state of California, this statement is not true. Your vehicle does however need a converter that will work on your vehicle. All the converters listed in our online catalog work on the applications they are intended for, including California emission models, unless otherwise stated.

I have a GM/Honda/Toyota vehicle. I just replaced my catalytic converter and the engine light has come on. Why is this?
Some vehicles have very strict tolerances on catalytic converter performance and if the correct replacement parts are not used, the engine light will be turned on to indicate that there is a problem with the converter. It is very important that the correct parts be used and installed correctly to avoid potential problems. It is also extremely important to understand that the reason the original converter failed has to be addressed, or the replacement converter may be damaged.

My car has a lot of miles on it and I am concerned that my catalytic converter needs replacement. Should I replace my converter as preventative maintenance?
A catalytic converter has no moving parts and does no wear out. While there are a number of things that can cause them to fail, if the vehicle is kept in proper operating condition with regular tune ups, the converter should last the life of the vehicle. If your converter has failed, there is usually a reason. The most common cause of catalytic converter failure is an improperly tuned vehicle.
What are LEV Converters
LEV is an acronym for Low Emission Vehicle. This designation is granted to various vehicles that meet certain emission standards. These standards are extremely stringent, requiring specialized catalysts. If your vehicle has an LEV sticker located under the hood, chances are that you will need an replacement converter that meets LEV standards.
Does my car require an LEV converter?
If the vehicle has an LEV sticker located underneath the hood, than chances are that you will need an LEV compliant converter as a replacement. Vehicles that meet LEV standards and require special LEV converters include most Honda, Toyota, GM, and Volkswagen vehicles made after 1996. Some vehicle which may not have the LEV designation may also require LEV catalysts. Such applications include many BMW and Mercedes models.
My car runs on natural gas. Do I require a special converter for my car?
There is not a simple answer to this question as there are many different types of vehicles. Also whether the vehicle came from the factory as a natural gas vehicle or has been converted by an independent installer can make a difference as to the vehicles performance and catalyst performance.

In many applications natural gas (CNG) does pose significant challenges to the converters. CNG does not normally burn at low temperatures, and it has proven to be difficult to provide a consistent catalytic reaction with CNG at the temperatures typically found in an exhaust system. CNG normally burns at temperatures around 1200 degrees, but most exhaust systems operate between 320 - 600 degrees. With the proper blend of catalyst materials, desirable catalyst function can still be achieved. We do carry some direct fit parts intended specifically for CNG vehicles. Our LEV converters are also suitable for CNG applications.
