                            EXECUTIVE ORDER D—182—35

                         Relating to Exemptions under Section 27156
                                   of the Vehicle Code

                           Walker Manufacturing Company

WHEREAS, Vehicle Code Sections 27156 and 38391, and Title 13, California Code of
Regulations (hereafter "CCR") Section 2222(h), authorize the California Air Resources Board
(ARB) and its Executive Officer to exempt new aftermarket catalytic converters from the
prohibitions of Vehicle Code Section 27156.

WHEREAS, Walker Manufacturing Company (Walker), a Tenneco Automotive Division, of
2701 N. Dettman Road, Jackson, Michigan 49201, has applied to the ARB for exemption from
the prohibitions in Vehicle Code Sections 27156 and 38391 to market their Series 99300 new
aftermarket three—way plus oxidation catalytic converter (TWC + OC) for the following
applications, except for vehicles equipped with an On—Board Diagnostic If (OBD—II) system (Title
13, CCR, Section 1968.1):

Converter Type   Series Number_|    Converter Use   Max. Eng. Size          Max. Veh. Test Wt.
TWC + OC         99300              TWC + OC,       5.9L (360 C1D)          6,000 Ibs. (GVWR =

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 ARB finds that the above aftermarket
catalytic converter complies with the California Vehicle Code Section 27156 and Title 13, CCR,
Section 2222(h). Emission performance of the catalytic converter was based on durability
bench aging conducted by Johnson Matthey Catalyst Systems Division using the ARB—modiffied
RAT—A bench—aging procedures in lieu of the 25,000—mile AMA driving cycle (Reference
Appendix IV, Title 40, part 86, Code of Federal Regulations (June 28, 1977)).

WHEREAS, emissions tests conducted at Automotive Testing and Development Services
(ATDS) laboratory, Ontario, California, using a 1989 5.9L Dodge Ram Van, and a 1995 5.9L
Dodge Pickup 2500 showed the following conversion efficiencies which meet the minimum
requirements for new aftermarket catalytic converters:

IT IS HEREBY RESOLVED that the above catalytic converter is exempt from the prohibitions in
Vehicle Code Section 27156 for installation on the approved application vehicles subject to the
foliowing 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
             ARB 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 applications other than the ones shown in this Executive
             Order shall be prohibited unless prior approval is obtained from the ARB.
             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 contents by Walker
             Manufacturing Company, 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 emission
             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.

             Walker Manufacturing Company‘s installation instructions for the new catalytic
             converter must conform to requirements in Paragraphs | and IX of California
             Evaluation Procedures for New Aftermarket Non—Original Equipment Catalytic
             Converters.

             Upon instaliation, the catalytic converter must carry a manufacturer‘s warranty for
             25,000 miles on the substrates and 50,000 miles or five years on the shell and
             end pipes.

            Walker Manufacturing Company and its vendors may not advertise the new
            aftermarket catalytic converter as a "high flow", "easy flow", or "Clean Air" catalytic
            converter or use any phrase that could make it appear to perform better than the
            OEM catalytic converter.

WALKER MANUFACTURING COMPANY — CATALYTIC CONVERTER — D—182—35


                                        EVALUATION SUMMARY

Manufacturer Name: Walker Manufacturing Company

Name of Device: Series 99300 Three—way plus oxidation catalytic converter (TWC + OC).

Background:
             Walker Manufacturing Company (Walker) of 2701 North Dettman Road, Jackson,
Michigan 49201, has applied for an exemption from the prohibitions in Section 27156 of the
California Vehicle Code (VC ) for its Series 99300 new aftermarket TWC + OC. The new
aftermarket catalytic converter is for installation on vehicles with maximum engine displacement
of 5.9L and an equivalent test weight of 6,000 pounds, except for vehicles equipped with On—
board Diagnostic II (OBD II) systems. It was also tested for TWC application.

Recommendation:
          Grant exemption to Walker as requested, and issue Executive Order
D—182—35.

Device Description:
            Walker‘s new aftermarket TWC + OC is designed to use two oval ceramic monolith
substrates. The dimensions of the substrates are 5.70 inches for the major axis, 3.20 inches for
the minor axis, and 2.0 inches in length. The volume of each substrate is 30.89 cubic inches.
The substrates are contained in a shell constructed from 409—grade stainless steel. The
substrates are wrapped with intumescent mat, to prevent vibration and exhaust by—pass. The
shell is sealed by seam weld, and a piece of aluminized heat shield is spot—welded to the upper
side of the converter to protect the vehicle underbody from excessive heat. The catalytic
converter may be soid as universal or direct fit, with installation instructions. It comes with a
warranty for 25,000 miles on the substrates, and five years or 50,000 miles on the container or
shell, and the end pipes.
             Johnson Matthey Environmental Catalysts and Technologies Division (Johnson
Matthey) of Wayne, Pennsylvania, is the catalyst supplier for Walker‘s Series 99300 TWC +
OC.

Discussion/Basis for Exemption Recommendation:
                 Walker submitted data on the Series 99300 TWC + OC from testing
conducted at Automotive Testing and Development Services (ATDS) laboratory, Ontario,
California. Johnson Matthey performed the catalyst bench aging using ARB—modified RAT A
bench aging cycle for 50 hours. Emission tests were conducted using a 1995 5.9L Dodge Ram
2500 truck for the TWC application and a 1989 5.9L Dodge Ram Van for the TWC + OC
application.                                          .
             The evaluation of the new aftermarket catalytic converter is based on the
bench—aging by Johnson Matthey and emission tests conducted at ATDS. The limits of
application of Walker‘s Series 99300 TWC + OC will be 5.9L/6,000 Ibs. The test catalysts were
labeled 12505A and 12505C. Testing consisted of two cold—start CVS—75 tests with a simulator
("dummy" catalyst), followed by two cold—start CVS—75 tests for each of the test catalysts. The
average of the two test results for each test catalyst was used to calculate the conversion
efficiency. The overall conversion efficiency for the catalyst model is the average conversion
efficiency of the two test catalysts.   The test results for the Series 99300 catalyst are shown
below:

The above test results meet the minimum requirements of the California regulations on new
aftermarket catalytic converters. The Air Resources Board (ARB) did not conduct confirmatory
tests on the new aftermarket catalytic converter.
