California Catalytic Converters
Effective January 1, 2009
Catalytic Converter Case Stamping

The Run Down: What this means is that all catalytic converters used for vehicles that are California OBD 1 (vehicles mostly made before 1996) and OBD 2 will have to use catalytic converters that have a stamp, on the converter, from the ARB(Air Resources Board) to pass smog in California. The smog stations are already set-up to run the number on the catalytic converter through their computers when you come in. If you have a number that is not specific to your vehicle, you will not pass smog.

If you have any questions you can contact us for the listing of your vehicle. We are in complete compliance for the state of California and have the correct converter for your vehicle to pass smog. Bob's Muffler is not a certified smog station, but we are authorized to install any and all legal catalytic converters on vehicles.


VEHICLE APPLICATION CATALOG INSTRUCTIONS - Application look-up will no longer be based upon G.V.W. (Gross Vehicle Weight) and engine size. Application look-up is the only approved method for determining the correct part number. It is illegal to select a catalytic converter for installation based solely on vehicle weight, engine size, physical shape, size, configuration or pipe diameter.

For non-OBD-II vehicles, the application list will identify the vehicle based on the categories below:

(PC-1): Passenger car single configuration.
(T-1): Truck single configuration.
(PC-2): Passenger car dual configuration.
(T-2): Truck dual configuration.

DETERMINING SINGLE AND DUAL CONFIGURATIONS - A single configuration refers to vehicles with an OEM catalytic converter configuration consisting of a single catalytic converter per bank.

A dual configuration refers to vehicles with an OEM catalytic converter configuration with two or more catalytic converters inline per bank.

IDENTIFYING NEW AFTERMARKET CATALYTIC CONVERTERS - As of January 1st, 2009, what you need to look for to ensure you are selling, buying or installing California LEGAL catalytic converters:

The body should be clearly labeled with the following:
# A.R.B.- EO Number: (example: D-193-88)
# Part Number: (example: 34015)
# Date Code: (example: 0109)
# Directional Flow Arrow
# 1/2" Tall Numbers

(A) The vehicle is specifically included in the vehicle application list for which the new aftermarket catalytic converter has been exempted;

(B) The vehicle is more than 7 years old or has more than 70,000 miles on its odometer;

(C) The vehicle is beyond the coverage of the OEM catalyst warranty period (which can vary from 7 years or 70,000 miles to as high as 15 years or 150,000 miles).2 Installers may reference the vehicle owner’s manual/warranty booklet or contact the vehicle manufacturer or its representative to verify the applicable OEM catalyst warranty;

(D) The vehicle has a legitimate need for replacement of the existing converter that has been established and documented by the installer on the repair invoice. If the OEM converter is present, the installer must make a determination that it is not functioning properly before acting to replace it;

(E) The exempted new aftermarket catalytic converter is installed in the same location as the OEM catalytic converter it is designed to replace. The front face of the installed catalytic converter shall be no more than three inches further upstream or downstream in the exhaust from where the front face of the OEM catalytic converter was located. The installation may not alter the location, position, or orientation of oxygen sensors upstream and downstream of the catalytic converter(s);

(F) The exempted new aftermarket catalytic converter is installed on a one-for one catalytic converter (not substrate) basis;

(G) The exempted new aftermarket catalytic converter is installed with all other required catalytic converters (no consolidation of catalytic converters, nor addition of extra catalytic converters is allowed); and
