                               EXECUTIVE ORDER D—691

                      Relating to Exemptions Under Section 27156
                                     of the Vehicle Code

                                  Weistec Engineering
                               M156 Weistec Supercharger

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—02—003;

IT IS ORDERED AND RESOLVED: That the installation of the M156 Weistec Supercharger
manufactured and marketed by Weistec Engineering of 1701 E. Edinger Avenue, Suite G4,
Santa Ana, CA 92705, 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 Code for the Mercedes Benz vehicle applications listed in Exhibit A.

The M156 Weistec Supercharger includes the following main components: a supercharger
blower and intake manifold plenum, fuel rails, an air to—water intercooler, and new fuel and
timing map calibrations. A longer manifold air pressure harness is used in conjunction with
the relocated sensor on the supercharger manifold. All other emission—related components
are in the stock location relative to the throttle body. All crankshaft pulleys are stock and
maximum boost is limited to 6 psi.

This Executive Order is valid provided that the installation instructions for the M156 Weistec
Supercharger will not recommend tuning the vehicle to specifications different from those of
Weistec Engineering.

Changes made to the design or operating conditions of the devices, as exempted by the Air
Resources Board, 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 Air Resources Board.

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.

This exemption is issued based on submitted emissions test data from an independent
laboratory on a 2011 model year Mercedes Benz C63 AMG (Test Group BMBXVO6.3U2A)
certified to the Low Emission Vehicle I| Uitra Low Emission Vehicle (LEV I} ULEV) and
Supplemental Federal Test Procedure (SFTP) standards:

Test results showed that the M156 Weistec Supercharger when installed on the vehicle did
not cause exhaust emissions to exceed the applicable emission standards during the Cold—
Start Federal Test Procedure. This Executive Order is also based on On—Board Diagnostic 1|
(OBD !I) testing conducted the same test vehicle. The M156 Weistec Supercharger when
installed on this test vehicle did not affect the vehicle‘s ability to perform its OBD 11

The Air Resources Board 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.


No claims 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.
