                             EXECUTIVE ORDER D—193—50
                      Relating to Exemptions under Section 27156
                                   of the Vehicle Code

                  Car Sound Exhaust System, Inc. (d.b.a. Magnafiow)
            "Series 46000 OBD II Compliant Three—way Catalytic Converter"

WHEREAS, Vehicle Code Sections 27156 and Section 2222(h), Title 13, California Code of
Regulations (hereafter "CCR"), 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 Section 27156 to market its new aftermarket
Series 46000 three—way catalytic converter (TWC) for installation on selected 1996 through
1999 model year BMW passenger cars equipped with on—board diagnostic II (OBD—II)
systems as specified in Appendix D—193—50 and incorporated herein. The Series 46000
TWC will be used for single (one unit) or dual (two units) exhaust system applications for
selected BMW passenger cars.

Series 46000 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—50.

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, 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 Energy
and Chassis Systems using Air Resources Board—modified RAT—A bench—aging cycle for
75 hours, as specified in the "Optional Evaluation Procedures for New Aftermarket Non—
original Equipment Catalytic Converters Equipped with On—Board Diagnostic II (OBD II)

WHEREAS, emissions tests conducted at the Automotive Testing and Development
Services, Inc. (ATDS), Ontario, California, with Series 46000 TWC installed on a 1998 2.8L
BMW Z3, test group WBMXVO2.8735, certified to the passenger car, Transitional Low
Emission Vehicle emission standards (PC, TLEV), showed that the catalytic converter met
the applicable emission standards.

OBD II compatibility tests performed on the same test vehicle showed that Series 46000
TWC did not affect the vehicle‘s ability to perform OBD II system monitoring. Emission test
results in grams per mile are shown below.

IT IS HEREBY RESOLVED that the above catalytic converter is exempt from the prohibitions
in Vehicle Code Section 27156 for installation on the vehicles listed in Appendix D—193—50
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.

      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 Air
             Resources Board. Exemption of these products 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
             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.

      4.     Car Sound Exhaust System, Inc.‘s installation instructions for the new catalytic
             converter must conform to requirements in Paragraphs | and X of the "Optional
             Evaluation Procedures for New Aftermarket Non—original Equipment Catalytic
             Converters Equipped with On—Board Diagnostic !I (OBD I1) Systems."

      5.     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.

      6.     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 them appear to perform better than an OEM
             catalytic converter.

      7.     The new aftermarket catalytic converter substrate may not be sold or supplied
             to a third party by Car Sound, its associates, vendors, other businesses, and


                                         —   3   —

              individuals associated with Car Sound, to be assembled in a different facility
              and marketed under this Executive Order.

       8.     Any marketing arrangement of the new aftermarket catalytic converter by a third
              party, which involves the use of packaging identification different from the ones
              described in this Executive Order must be approved by Air Resources Board
              prior to shipment.

       9.     Car Sound must submiit the required quality audit and production quantity
              reports for its aftermarket catalytic converter serni—annually, covering the
              periods January 1 throughJune 30, and July 1 through December 31.

Violation of any of the above conditions shall be grounds for revocation of this order. The
order may be revoked only after a 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.

Executed at El Monte, California, this        / 9 day of July 2007.
