The applicable stock air cleaner housing lid with the hydrocarbon adsorber or the hydrocarbon adsorber puck in the intake on 2005 model year Mustangs built on or before April 30, 2005, and 2007 to 2009 model year Mustangs is retained but modified with a new air cleaner housing bottom, a new high flow filter and an air cleaner housing lid modified to accept the mass air flow (MAF) extension. The breather hose may be replaced with an SAE30R9 rated hose. Boost is limited to a maximum of 13 psi. The stock crankshaft pulley and throttle body are retained during installation. The Whipple Charger kit, for other Ford vehicles, consists of the following main components: Twin Screw Whipple supercharger, intake manifold, bypass valve, 160 degree thermostat to replace the stock thermostat, new air cleaner housing with a high-flow element, fuel pump, reflashed ECM, mass air flow sensor, and a set of high flow injectors. Some kits may include an intercooler. The breather hose may be replaced with an SAE30R9 rated hose.

                           Relating to Exemptions Under Section 27156
                                      of the California Vehicle Code

                                      Whipple Industries, Inc.
                                      Whipple 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 Whipple Supercharger,
manufactured and marketed by Whipple Industries, Inc., 3292 N. Weber, Fresno, California
93722, has been found not to reduce the effectiveness of the applicable vehicle pollution control|
systems and, therefore, is exempt from the prohibitions of Section 27156 of the Vehicle Code for
the Ford Motor Company vehicles listed in Exhibit A.

The Whipple Supercharger kit, part number WIK—4.6L—3V—IC and WIK—5.4L—3V, consists of the
following main components: 2.3L Twin Screw Whipple supercharger using a 3.125 to 4.0 inch
diameter pulley, intercooler, intake manifold, bypass valve, 160 degree thermostat to replace
the stock thermostat, fuel pump, reflashed ECM, mass air flow sensor, a set of high flow
injectors, and an open element air filter on 2005 model year Mustangs built after April 30, 2005
and 2006 model year Mustangs only. The applicable stock air cleaner housing lid with the
hydrocarbon adsorber or the hydrocarbon adsorber puck in the intake on 2005 model year
Mustangs built on or before April 30, 2005, and 2007 to 2009 model year Mustangs is
retained but modified with a new air cleaner housing bottom, a new high flow filter and an air
cleaner housing lid modified to accept the mass air flow (MAF) extension. The breather hose
may be replaced with an SAE30R9 rated hose. Boost is limited to a maximum of 13 psi. The
stock crankshaft pulley and throttle body are retained during installation.

The Whipple Charger kit, for other Ford vehicles, consists of the following main components:
Twin Screw Whipple supercharger, intake manifold, bypass valve, 160 degree thermostat to
replace the stock thermostat, new air cleaner housingwith a high—flow element, fuel pump,
reflashed ECM, mass air flow sensor, and a set of high flow injectors. Some kits may include
an intercooler. The breather hose may be replaced with an SAE30R9 rated hose.

This Executive Order is valid provided that the installation instructions for the Whipple
Supercharger will not recommend tuning the vehicle to specifications different from those
submitted by the device manufacturer.

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


 This Executive Order shall not apply to any Whupple Supercharger advertised, offered for sale,
 sold with, or installed on a new motor vehicle prior to or concurrent with transfer to an ultimate _
 purchaser.

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

  This Executive Order is granted based on submitted emission test data generated on a
  2007 model year 4.6L Ford Mustang certified to the Low Emission Vehicle II Ultra Low Emission
  Vehicle (LEV 1| ULEV) emission standards and modified with the Whipple Supercharger Kit,
  part number WIK—4.6L—3V—IC using the 2.3L compressor and the 3.125 inch diameter
 supercharger pulley. Test results showed that emission levels, with Whipple Industries, Inc.‘s
  Whipple Supercharger installed, met the applicable emission standards when tested using the
  Cold—Start CVS—75 Federal Test Procedure (FTP) and the Supplemental Federal Test
  Procedure (SFTP USO6/SC03) test cycles. Boost pressure was measured at 13 psi.
  Examination of the OBD II system showed the Whipple Supercharger did not affect OBD II
  system operation. Results from emission testing conducted at the Roush Emissions
  Laboratory, Livonia, Michigan are listed below with deterioration factors applied.
