                              EXECUTIVE ORDER D—488—2
                       Relating to Exemptions Under Section 27156
                                    of the Vehicle Code

                        MAGNA CHARGER CORPORATION        -

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 Section 39515 and Section
39516 of the Health and Safety Code and Executive Order G—45—9;

IT IS ORDERED AND RESOLVED: That the installation of the General Motors 5.3L.
Supercharger kit manufactured and marketed by Magna Charger Corporation of 3172
Bunsen Avenue, Unit D, Ventura, California 93003 has been found not to reduce the
effectiveness of required motor vehicle pollution control devices and, therefore, is
exempt from the prohibitions of Section 27156 of the California Vehicle Code for the
1999 model—year 5.3L Chevrolet Silverado and GMC Sierra, part number 153—001 and
the 2000 model—year 5.3L Chevrolet Silverado, Tahoe, Suburban and GMC Sierra,
Yukon and Yukon XL, part number 153—002.

The General Motors 5.3L Supercharger Kit includes the following main components:
Eaton supercharger with a 3.4" pulley, intake manifold plenum and throttle body
adapter. New fuel injectors, part number 171 13553, are utilized to upgrade the 1999
model—year vehicles in order to have the same injectors as the 2000 model—year
vehicles. The throttle body is moved to the supercharger inlet. The EGR valve is
relocated onto the inlet duct between the throttle body and the supercharger in order to
preserve stock EGR function. All other emission—related components are in the stock
location relative to the throttle body. —

This Executive Order shall not apply to any Magna Charger Genéeral Motors 5.3L
Supercharger Kit advertised, offered for sale, sold with, or installed on a new motor
vehicle prior to or concurrent with transfer to an ultimate purchaser.

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

Changes made to the design or operating conditionsof the device, as exempted by the
Air Resources Board (ARB), that adversely affect the performance of a vehicle‘s
pollution control system shall invalidate this Executive Order.

MAGNA CHARGER CORPORATION                                  EXECUTIVE ORDER D—4882
GM 5.3L SUPERCHARGER KIT                                   (Page 2 of 3)

Marketing of this device using any identification other than that shown in this Executive
Order or marketing of this device for an application other than those listed in this
Executive Order shall be prohibited unless prior approval is obtained from the ARB.

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

This exemption is issued based on submitted emissions test data from an independent
laboratory which showed that the supercharger kit did not adversely affect exhaust
emissions of the tested vehicle. The test results are shown below.

Test results showed that the supercharger kit when instailed on the vehicle did not
cause tailpipe emissions to exceed the vehicle‘s applicable emission standards during
the Cold Stait CVS—75 Federal Test Procedure. This Executive Order is also based on
the On—Board Diagnostic II (OBD II) testing conducted on the same test vehicle. Test
data showed that the supercharger kit when installed on the vehicle did not affect the
vehicle‘s ability to perform its OBD II monitoring.

However, the ARB finds that reasonable grounds exist to believe that use of the Magna
Charger Corporation‘s General Motors 5.3L Supercharger Kit may adversely affect
emissions of motor vehicles when operating under conditions outside the parameters of
the previously prescribed test procedures. Accordingly, the ARBreserves 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 supercharger kit adversely affects emissions during off—cycle
conditions (defined as those conditions which are beyond the parameters of the Cold—
Start CVS—75 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 provides the ARB with reason to suspect that the supercharger kit will
affect durability of the emission control systems, Magna Charger Corporation 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 modified part
demonstrates adequate durability.

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 Title 13,
California Code of Regulations, Section 2222, et seq.
