Catalytic Converters

California Approved Converters News


Beginning January 1, 2009 California Air Resources Board (C.A.R.B.) changed the law pertaining to all aftermarket catalytic converters for the California market.

This new law firmly states that the California EO Number (Executive Order) must physically appear directly on the converter.  The basis of the new law is explained below.  We at Discount Converter are updating our database almost on a daily basis to bring online these new numbers.  Even though you may not find your vehicle in our database…WE CAN STILL HELP YOU!  Following is the procedure to find a California approved Catalytic Converter for your vehicle:

New C.A.R.B. requirements for Aftermarket Catalytic Converters in California.

New C.A.R.B. regulations (effective 1-1-09) change the requirements of aftermarket catalytic converters sold in CA. The new regulations require that catalytic converters meet low emission vehicle (LEV) standards, a significant improvement in performance over the current generation catalysts.

These new regulations are limited to catalysts sold in CA, and do not effect catalysts sold in the other 49 states.

In addition all aftermarket converters sold or installed in the state of California must bear an Executive Order (EO Tag) stamp issues by CARB (California Air Resources Board).

Discount Converter, Ltd. will be able to provide CA legal catalysts for the California market that meet all C.A.R.B requirements as they are approved by the California Air Resources Board.


Q: Under the new regulation will my old pre-OBD II converters pass smog?
A: Yes, as long as it was installed before 1/1/09 and the vehicle meets the applicable emissions standards.

Q: I assume with a higher performance converter comes a higher price, what is the benefit of this additional cost?
A: C.A.R.B. studies have shown that by 2012, they expect to realize a decrease in emission levels of HC by 10,600lbs per day*, and NOx by 62,600lbs per day*. In addition, a potential reduction of CO by 102,600lbs per day is expected to be realized.

California has been through new C.A.R.B. regulations before, and the end result will be short term inconvenience and long term air quality improvements.
