                      Relating to Exemptions Under Section 27156
                                       of the Vehicle Code

Pursuant to the authority vésted in the Air Resourcés 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—02—003;

IT IS ORDERED AND RESOLVED: That the installation of the Radix Supercharger
Kit manufactured and marketed by Magnuson Products, Inc. of 3172 Bunsen Avenue,
Unit K, Ventura, CA 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 Vehicle Codeé for the 4.8L, 5.3L, and 6.OL
General Motors vehicles listed in Exhibit A.                            '

The Radix Supercharger Kit includes the following main components: Eaton
supercharger and intake manifold plenum, larger fuel injectors, air intake filter, air—to—
water intercooler, and new fuel and ignition timing map calibrations. The stock fuel
pressure regulator is retained, but the stock fuel pump is complemented with a
secondary fuel pump. The throttle body is moved to the supercharger inlet. All other
emission—related components are in the stock location relative to the throttle body. >
The supercharger pulley specifications range between 3.1" to 3.7" depending on the
engine displacement for which the kit is installed. All crankshaft pulleys are stock and
maximum boost is limited to 7 psi.

This Executive Order shall not apply to any Radix 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 for the Radix
Supercharger Kit 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 devices, 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.

Marketing of these devices 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
these devices may have on any warranty either expressed or implied by the vehicle
manufacturer.              1e ann wen memiasl —                              umces

This exemption is issued based on previously submitted emissions test data from an
independent laboratory on a 2004 model year General Motors Silverado 1500 2WD
vehicle (Test Group 4GMXT06.0187) certified to the Super Ultra Low Emission
Vehicle (SULEV) and Supplemental Federal Test Procedure (SFTP) standards:

Test results showed that the Radix Supercharger Kit when installed on the vehicle did
not cause exhaust emissions to exceed the applicable emission standards during the
Cold Start CVS—75 Federal Test Procedure or SFTP cycles. This Executive Order is
also based on the On—Board Diagnostic II (OBD I1) testing conducted on the same
test vehicle. The Radix Supercharger Kit when installed on the test vehicle did not
affect the vehicle‘s ability to perform its OBD I! monitoring.
