State of California AIR RESOURCES BOARD 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: Federal Test Procedure: NMOG CO NOX HCHO Standards (g/mi) 0.055 2.1 0.07 11 Device (g/mi) with df‘s applied 0.027 0.5 0.02 1 SFTP (USO6 Cycle}: NMHC+NOX co Standards (g/mi) 0.14 8.0 Device (g/mi) 0.02 1.3 SFTP (SCQ3 Alternative AC2 Cyclie}: NMHC+NOX CO Standards (g/mi) 0.20 2.7 Device (g/mi) 0.04 0.4 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 monitoring. 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.
