                                   EXECUTIVE ORDER D—161—72

                            Relating to Exemptions Under Section 27156
                                         of the Vehicle Code


                                       Gale Banks Engineering.

Pursuant to the authority vested in the Air Resources Board by Section 27156 of the Vehicle
Code; and _                      h000

Pursuant to the authority vested in the undersigned by Section 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 Duramax Stinger TLC,
manufactured and marketed by Gale Banks Engineering, 546 Duggan Avenue, Azusa, California
91702 has been found not to reduce the effectiveness of the applicable vehicle pollution control
system and, therefore, is exempt from the prohibitions of Section 27156 of the Vehicle Code for
the following applicable 2001 through 2003 model—year General Motors trucks equipped with the
6.6L diesel engine.

          Part No.                 Applications
          48676                    Non—catalyst, std. cab, long bed
          48677                    Non—catalyst, ext/crew cab, short bed
          48678                    Non—catalyst, ext/crew cab, long bed
          48679                    With—catalyst, std. cab, long bed
          48680                    With—catalyst, ext/crew cab, short bed
          48681                    With—catalyst, ext/crew cab, long bed

The Duramax Stinger TLC is a performance package that includes an add—on control module
installed in series with the factory control module, exhaust head pipe (non—catalyst models),              .
exhaust system down stream of the catalyst, wastegate actuator, and a replacement K&N style air
filter.                                                                                                >

This Executive Order shall not apply to any Gale Banks Engineering‘s Duramax Stinger TLC .
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 is valid provided that the installation instructions for the Duramax Stinger
TLC will not recommend tuning the vehicle to specifications different from those of the vehicle
manufacturer.

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


                                                   2.


Marketing of the Duramax Stinger TLC using any identification other than that shown in this
Executive Order or marketing of the Duramax Stinger TLC for 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 Duramax Stinger TLC 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 the use of the Duramax
Stinger TLC may have on any warranty either expressed or implied by the vehicle manufacturer.

This Executive Order is granted based on submitted emissions test data which showed that the
Duramax Stinger TLC did not adversely affect tailpipe emissions during a Cold—Start 505 Federal
Test Procedure. A 2002 model year General Motors K2500 with a 6.6L diesel engine, and
certified to the Low Emission Vehicle (LEV) emission standards was used as the test vehicle.

Exhaust emissions during comparative Cold Start 505 Federal Test Procedure showed that the
Duramax Stinger TLC did not cause emissions to exceed baseline levels by more than the allowed
limits of 10 percent or 0.1 grams per mile on hydrocarbon (HC) and oxides of nitrogen (NOx), 15
percent or 1.0 grams per mile carbon monoxide (CO), and 15 percent or 0.03 grams per mile on
Particulate Matter (PM) as specified in the "Procedures for Exemption of Add—On and Modified
Parts." Opacity test results were also below their applicable emission standard. This Executive
Order is also based on an On—Board Diagnostic II (OBD II) testing conducted on the same vehicle.
Test data showed that the Duramax Stinger TLC when installed on the vehicle did not affect the |
vehicle‘s ability to perform its OBD II monitoring.

The ARB finds that reasonable grounds exist to believe that use of the Duramax Stinger TLC may
adversely affect emissions of motor vehicles when operating under conditions outside the
parameters of the Cold—Start 505 Federal Test Procedure. Accordingly, the ARB reserves the right
to conduct additional emission tests, in the future, as such tests are developed, that will more
adequately measure emissions from all cycle phases. If such test results demonstrate that the:
Duramax Stinger TLC adversely affects emissions during off—cycle conditions (defined as those
conditions which are beyond the parameters of the Cold Start 505 Federal Test Procedure), this _
Executive Order shall be effectively rescinded as of the date the test results are validated.
Further, if such test results or other evidence provide the ARB with reason to suspect that the
Duramax Stinger TLC will affect the durability of the emission control system, Gale Banks
Engineering shall be required to submit durability data to show that the durability of the vehicle
emission control system is not, in fact, affected and/or that the add—on or modified part
demonstrateés adequate durability.

                                                 L300


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 Title 13, California Code of Regulations, 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 GALE BANKS ENGINEERING‘S DURAMAX STINGER TLC.

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.

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.

Executed at El Monte, California, this _ [77’{ day of July 2003.
