                               EXECUTIVE ORDER D—167—26
                                Relating to Exemptions under
                             Section 27156 of the Vehicle Code

                                    Hedman Hedders
                            Tubular Exhaust Manifold Systems

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

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

IT IS ORDERED AND RESOLVED: That installation of the Tubular Exhaust Manifold
Systems, manufactured by Hedman Hedders of 12436 Putnam Street, Whittier,
California 90602, has been found not to reduce the effectiveness of the applicable
vehicle pollution control system, and therefore, the Tubular Exhaust Manifold Systems
are exempt from the prohibitions in Section 27156 of the Vehicle Code for installation on
the vehicles listed in Attachment A.

This Executive Order is based on previous Cold—Start CVS—75 Federal Test Procedure
emissions and On—Board Diagnostic l1 System tests Hedman Hedders conducted with
its Tubular Exhaust Manifold Systems.

This Executive Order is valid provided that installation instructions for the Tubular
Exhaust Manifold Systems do not recommend tuning the vehicles to specifications
different from those of the vehicle manufacturer.

Changes made to the design or operating conditions of the Tubular Exhaust Manifold
Systems, as exempt by the ARB, which adversely affect the performance of the
vehicle‘s emission control system, shall invalidate this Executive Order.

Marketing of the Tubular Exhaust Manifold Systems using identification other than that
shown in this Executive Order or for an application other than that listed in this
Executive Order shall be prohibited unless prior approval is obtained from the ARB.

Exemption of the Tubular Exhaust Manifold Systems shall not be construed as
exemption to sell, offer for sale, or advertise any component of the system as an
individual device.

This Executive Order shall not apply to any Tubular Exhaust Manifold Systems
advertised, offered for sale, sold with, or installed on a motor vehicle prior to or
concurrent with transfer to an ultimate purchaser.

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


                                              2.

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 or other oral or written
communication.

In addition to the foregoing, the ARB reserves the right in the future to review this
Executive Order and the exemption provided herein to assure that the exempted add—on
or modified part continues to meet the standards and procedures of California Code of
Regulations, Title 13, Section 2222, et seq.

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 THE APPLICANT CONCERNING
ANTI—POLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF HEDMAN
HEDDERS‘ TUBULAR EXHAUST MANIFOLD SYSTEMS.

Violation of any of the above conditions shall be grounds for revocation of this Executive
Order. The Executive Order may be revoked only after a ten—day written notice of
intention to revoke the Executive Order, in which period the holder of the Executive
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 Executive
Order may not be revoked until a determination is made after the hearing that grounds
for revocation exist.

Executed at El Monte, California, this     ?5‘5”&   day of April 2004.
