                                     State of California
                                 AIR RESOURCES BOARD


                              EXECUTIVE ORDER D—165—9
                       Relating to Exemptions Under Section 27156
                                    Of the Vehicle Code


                              Downey Off Road Manufacturing
                                    Exhaust Headers


Pursuant to the authority vested in the Air Resources Board by Section 27156 of the
Vehicle Code; and

Pursuant to the authority vested in the undersigned by Sectioh 39515 and Section 39516
of the Health and Safety Code and Executive Order G—02—003;

IT IS ORDERED AND RESOLVED; That the installation of the Exhaust Headers
marketed by Downey Off Road Manufacturing, 10001 S. Pioneer Boulevard, Santa Fe
Springs, California 90670—3221 has been found not to reduce the effectiveness of the
applicable vehicle pollution control systems and, therefore, is exempt from the
prohibitions of Section 27156 of the Vehicle Code for the truck applications listed in
Exhibit A, excluding any vehicle certified to Ultra Low Emission Vehicle (ULEV) or lower
emission standards.

This Executive Order is valid provided that the installation instructions for Exhaust
Headers will not recommend tuning the vehicle to specifications different from those of
the vehicle manufacturer.

This Executive Order shall not apply to any Downey Off Road Exhaust Headers
advertised, offered for sale, sold with, or installed on a motor vehicle prior to or
concurrent with the transfer to an ultimate purchaser.

Changes made to the design or operating conditions of Exhaust Headers, as exempt by
the Air Resources Board, which adversely affect the performance of the vehicle‘s
pollution control system shall invalidate this Executive Order.

Marketing of the Exhaust Headers using any identification other than that shown in this
Executive Order or marketing of the Exhaust Headersfor an application other than those
listed in this Executive Order shall be prohibited unless prior approval is obtained from
the Air Resources Board. Exemption of the system shall not be construed as exemption
to sell, offer for sale, or advertise any component of the kit as an individual device.


This Executive Order does not constitute any opinion as to the effect that the use of the
Exhaust Headers may have on any warranty either expressed or implied by the vehicle
manufacturer.

This Executive Order is granted based on the following submitted emissions test data on
a 1999 Toyota 4Runner equipped with a 3.4 liter engine and certified to the Low
Emission Vehicle (LEV) emission standard:

                     NMOG          CO       NOx   HCHO
Standards            0.100         4.4     0.4    0.018
Device w/dfs         0.089         0.7     0.3    0.004

Test results showed that tailpipe emissions with the Exhaust Headers installed on the
vehicle met the vehicle‘s emission standard during a Cold Start CVS—75 Federal Test
Procedure. This Executive Order is also based on On Board Diagnostic II (OBDI!)
testing conducted on the same test vehicle. Test data showed that the header when
installed on the vehicle did not affect the vehicle‘s ability to perform OBDII monitoring.

THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION,
ACCREDITATION, APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE
AIR RESOURCES BOARD OF ANY CLAIMS OF TH EAPPLICANT CONCERNING
ANTI—POLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF DOWNEY OFF
ROAD MANUFACTURING‘S EXHAUST HEADERS.

No claim of any kind, such as "Approved by the Air Resources Board", may be made
with respect to the action taken herein in any advertising of other oral or written
communication.

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 the
order, in 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.

Executive Order D—165—7, dated October 2000, is superseded and of no further force and
effect.

Executed at El Monte, California, this /@fl" day of May 2002.
