"THREE—WAY CATALYTIC CONVERTER SERIES 43000" WHEREAS, Vehicle Code Sections 27156, and Title 13, California Code of Regulations (hereafter "CCR") Section 2222(h), authorize the California Air Resources Board and its Executive Officer to exempt new aftermarket catalytic converters from the prohibitions of Vehicle Code Section 27156. WHEREAS, Car Sound Exhaust System, Inc. (Car Sound) of 22961 Arroyo Vista, Rancho Santa Margarita, California 92688, has applied to the Air Resources Board for exemption _ from the prohibitions in Vehicle Code Sections 27156 to market its new aftermarket series 43000 three—way catalytic converter (TWC) for selected 2003 and older General Motors trucks equipped with an on—board diagnostic II (OBD—II) system as specified in Appendix D—193—51 and incorporated herein. The application coverage excludes vehicles equipped with a warm—up catalyst. Series 43000 TWC will be used in dual parallel underbody or single underbody vehicle applications. Series 43000 TWC may also be installed on non—OBD II vehicles (1995 and older) similar in engine and exhaust configuration to those listed in Appendix D—193—51. ' WHEREAS, pursuant to the authority vested in the Executive Officer by Health and Safety Code Section 39515 and in the Chief, Mobile Source Operations Division by Health and Safety Code Section 39516 and Executive Order G—02—003, the Air Resources Board finds that the above aftermarket catalytic converter complies with the California Vehicle Code Section 27156 and Title 13, California Code of Regulations, Section 2222(h). The emissions performance of the catalytic converter was based on durability bench—aging by Delphi Engine and Chassis Systems using the ARB—modified RAT—A bench—aging cycle for 100 hours, as specified in the "Optional Evaluation Procedures for New Aftermarket Non—original Equipment Catalytic Converters Equipped with On—Board Diagnostic II (OBD I!) Systems." WHEREAS, emissions tests conducted at the Automotive Testing and Development Services, Ontario, California, using a 1999 5.7L Chevrolet Tahoe, test group XGMXAO05.7185, certified to the Medium—Duty Vehicle 2, Low Emission Vehicle emission standards (MDV2, LEV), showed that the vehicle met the applicable emission standards with Series 43000 TWC (2 units) installed. The following are the test results in grams per mile: nmos _ co NOx MDV2 120K LEV standards 0.230 6.4 0.6 Average Series 43000 TWC Test Results 0.125 2.5 0.2 CAR SOUND EXHAUST SYSTEM, INC. — CATALYTIC CONVERTER — D—193—51

2. IT IS HEREBY RESOLVED that the above catalytic converter is exempt from the prohibitions in Vehicle Code Section 27156 for installation on the approved vehicle applications specified in Appendix D—193—51 subject to the following conditions: 1. No changes are permitted to the catalytic converter as described in the application for exemption. Any changes to the catalytic converter or any of its components, and other factors addressed in this order must be evaluated and approved by the Air Resources Board prior to marketing in California. Marketing of the catalytic converter using identifications other than those shown in the exemption application, and in this Executive Order, or marketing of the catalytic converter for application other than the ones shown in this Executive Order shall be prohibited unless prior approval is obtained from the Air Resources Board. Exemption of this product shall not be construed as an exemption to sell, offer for sale, or advertise any components of the catalytic converter as individual devices. Any oral or written references to this Executive Order or its content by Car Sound Exhaust System, Inc., its principals, agents, employees, distributors, dealers, or other representatives must include the disclaimer that the Executive Order or the exemption it provides is not an endorsement or approval of any ernission reduction claims for the catalytic converter and is only a finding that the catalytic converter is exempt from the prohibitions of Vehicle Code Section 27156. Car Sound Exhaust System, Inc.‘s installation instructions for the new catalytic converter must conform to requirements in Paragraphs | and xX of the "Optional Evaluation Procedures for New Aftermarket Non—original Equipment Catalytic Converters Equipped with On—Board Diagnostic II (OBD II) Systems." Upon installation, the catalytic converter must carry a manufacturer‘s warranty for 50,000 miles on the substrates and 50,000 miles or five years on the shell and end pipes. Car Sound Exhaust System, Inc. and its vendors may not advertise the new aftermarket catalytic converter as a "high or easy flow" catalytic converter or use any phrase that could make it appear to perform better than an OEM catalytic converter. Car Sound Exhaust System, Inc., its associates, vendors, other businesses, and individuals may not sell or supply the substrate of the new aftermarket catalytic converter to a third party to be assembled in a different facility and marketed under this Executive Order.
