California  Code of Regulations (hereafter "CCR") Section 2222(h),

oxidation catalytic converter (TWC + OC) for the following
application, except vehicles equipped with OBD II system:

EDCS3 for 25 hours in lieu of mileage accumulation of 25,000 miles
using the AMA durability driving schedule (Reference Appendix IV,
Title 40, part 86,       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

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


    3.   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 emissions 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.

    4.   Car Sound Exhaust System, Inc. installation instructions for
         the new catalytic converter must conform to requirements in

         manufacturer‘s warranty for 25,000 miles on the substrates and
         50,000 miles or five years on the shell and end pipes.

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 hearing is requested, it shall be held
within ten days of receipt of the request, and the order may not be
revoked until a determination is made, after the hearing, that grounds
for revocation exist.
