                          Relating to Exemptions Under Section 27156
                                     of the Vehicle Code


                              MAREMONT EXHAUST PRODUCTS, INC.
                      "NEW AFTERMARKET THREE—WAY CATALYTIC CONVERTER"

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, Maremont Exhaust Products,                Inc. of 2400 Industrial Park, Loudon,
Tennessee 37774, has applied to the ARB for exemption from the prohibitions
in Vehicle Code Sections 27156 and 38391 for their new aftermarket three—way
catalytic converter (TWC)            for the following application:

Converter           Use          Part Number   .             Max.   Eng.   >      Max.   Test
Iype                                                         Size                 Weight
TWC        c        TWC          29001,29002, 29003          2.5L (151 CID) 3,375 lbs.

The catalysts can be used to replace non—functioning original equipment
manufacturer         (OEM)   catalysts on fuel injected vehicles that are no longer
under vehicle manufacturer‘s emission control systems warranty, if the need
for the replacement is established.

WHEREAS, pursuant to the authority vested in the Executive Officer by Health
and Safety Code Section 39515 and in the Chief, Mobile Source Division by
Health and Safety Code Section 39516 and Executive Order G—45—9, the ARB
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).  Emission performance of the catalytic
converter was based on durability mileage accumulation of 25,000 miles using
the AMA durability driving schedule (Reference Appendix IV, Title 40, part
B6, Code of Federal Regulations (June 28, 1977)).

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 following conditions:

      1.       No changes are permitted to the converter as described in the
               application for exemption.  Any changes to the 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.

  2.           Marketing of the converter using identifications other than those
               shown in the exemption application, and in this Executive Order, or
               marketing of the converter for application other than the ones listed
               in the submitted application catalog 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 converter as individual devices.

   3.   Any oral or written references to this Executive Order or its content
        by Maremont Exhaust Products, 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 emissions reduction
        claims for the catalytic converter and is only a finding that the
        converter is exempt from the prohibitions of Vehicle Code Section
        27156.

   4.   Upon installation, 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.

   5.    Maremont must submit production audit test data for the catalyst to
        the ARB for review for the production audit reporting period of
        August 15, 1995, in accordance with Paragraph IX of California
        Evaluation Procedures for New Aftermarket Non—Original Equipment
        Catalytic Converters.   Thereafter,   the ARB may accept Maremont‘s
        quality control procedures as alternative to production audit
        testing for subsequent production audit report.

Violation of any of the above conditions shall be grounds for revocation of
this order.  The order may be revoked only after ten day written notice of .
intention to revoke it, during which period the holder of the order may
request in writing a hearing to contest the proposed revocation.  If a

I.        INTRODUCTION

          Maremont Exhaust Products,    Inc.   (Maremont) pf 2400 Industrial Park

Boulevard, Loudon, Tennessee 37774, has applied for an exemption from the

prohibitions in Vehicle Code Sections 27156 and 38391 for their new

aftermarket three—way catalytic converter (TWC) in accordance with

California regulations on new aftermarket catalytic converters.        The new

aftermgrket TWC is intended for use on light—duty fuel—injected vehicles as

shown below:

Maremont will market the catalytic converter as a post—warranty replacement

for applicable vehicles whose manufacturers‘ warranty has expired and the

need for replacement of the original equipment manufacturer (OEM) catalytic

converter has been established.

II.       CONCLUSION

          The applicant has submitted all the required information,     and based

on the submitted exhaust emissions test data, the staff concludes that the

catalytic converter meets the criteria set forth in Vehicle Code Section

27156 and Title 13, California Code of Regulations, Section 2222(h) for the

stated applications.

III.      RECOMMENDATION

          Staff recommends that the exemption be granted as requested and that

Executive Order No. D—184—10 be issued, permitting the advertisement,       sale,

and installation of the new aftermarket catalytic converter on applicable

vehicles.


Iv.        DEVICE DESCRIPTION

           Maremont‘s new aftermarket TWC contains two substrates.      The front

substrate is coated with palladium and rhodium in the ratio of 8:1, the rear

substrate is coated with palladium only.     Air tube is‘not required on the

conve?ter.     The front and rear substrates each measures 3.66 inches along

the major axis,    3.66 inches along the minor axis,    1.96 inches long,   and has

a volume of 20.62 cubic inches.     Front and rear metal loading is in the

ratio of 1:1.2.     The substrates are wrapped with compressed intumescent mat

to prevent vibration and exhaust gases from by—passing the catalyst.          The

substrates are enclosed in a stainless steel shell using seam welding.         A

heat shield of aluminized steel.is welded to the converter shell to protect

the vehicle underbody from heat.     The catalytic converter may be sold as a

unit with installation instructions and kits as shown in Maremont‘s

application catalog.     It is also sold with a warranty for 25,000 miles on

the substrates and five years or 50,000 miles on the container or shell.

v.         DEVICE EVALUATION

           Maremont submitted data from testing conducted by Roush Laboratories

in Livonia, Michigan.     Emissions tests were conducted on the following

vehicle:


Application      Emission Test Vehicle    Engine Size      ETW
TWC              1987 Grand AM            2.5L             3,375 lbs.

The Air Resources Board (ARB) did not conduct confirmatory tests on the new

aftermarket TWC due to heavy workload aE the ARB‘s Haagen—Smit Laboratory.

In lieu of confirmatory testing, the ARB is requiring Maremont tb conduct

product audit tests during the next production audit reporting period.         The

test results and conversion efficiencies for the converter are shown below:


                     Roush Laboratories, Livonia, Michigan

                                      IHC
            Simulator    Cat. A      Cat. B       AvgEff.
HC (g/mi)    1.259       0.221       0.242        81.6%
co (g/mi)    9.032       2.190       1.905        77.3%
Nox(g/mi}    1.277       0.446       0. 424       65.9%
The above conversion efficiencies meet the minimum requirements of the

California regulations on new aftermarket catalytic converters.
