                                    State of California
                                AIR RESOURCES BOARD

                                EXECUTIVE ORDER D—757

                       Relating to Exemptions Under Section 27156
                                  of the California Vehicle Code

                                   Singer Vehicle Design
                               Porsche 911 Engine Upgrade

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—14—012;

IT IS ORDERED AND RESOLVED: That the installation of the Porsche 911 Engine
Upgrade, manufactured and marketed by Singer Vehicle Design, 11585 Sheldon Street,
Unit B, Sun Valley, California 91352, 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 all 1990 to 1994 model year Porsche 911
vehicles.

The Singer Vehicle Design‘s Porsche 911 Engine Upgrade includes the following main
parts for the naturally aspirated engine: Cylinder heads, pistons, cylinders, crankshaft,
throttle bodies, fuel rails, high flow injectors, camshaft, connecting rods, 2 Car Sound
3—Way catalytic converters, p/n 456205, a pair of 3 into 1 16 gauge headers, oil cooler, fuel
pump, new fuel tank (same capacity as stock), fuel lines, new manual transmission, open
element air cleaner, and a new ECU with no user adjustments. Stock components that are
retained are the engine block and intake manifold. Overall displacement is increased from
a 3.6L to a 3.8L. Vehicles originally equipped with a turbo and intercooler must have these
part removed, and are not transferred to Singer Vehicle Design‘s Porsche 911 Engine
Upgrade.

This Executive Order is valid provided that the installation instructions for the Porsche 911
Engine Upgrade will not recommend tuning the vehicle to specifications different from those
of Singer Vehicle Design.

Changes made to the design or operating conditions of the Porsche 911 Engine Upgrade,
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 exemption is issued based on submitted emissions test data, from Automotive Testing
and Development Services, Inc., Ontario, California, on a 1990 model year Porsche 911
certified to the Tier 0 emission standards and tested using the Cold Start Federal Test
Procedure (FTP) test cycle and a Diurnal Heat Build + Hot Soak:


                                        CVS—75 FTP
                                   HCG       cCO   NOx
   Standards                       0.41      7.0   0.4
   Device                          0.28      11    0.2


   Diurnal Heat Build + Hot Soak

                  HC
   Standard       2.0
   Device         0.8

Test results showed that the Porsche 911 Engine Upgrade when installed on the vehicle
did not cause exhaust or evaporative emissions to exceed the applicable emission
standards during the FTP, SFTP, and 2 Day Diurnal. This Executive Order is also based
on the On—Board Diagnostic I (OBD 1) testing conducted on the same test vehicle. The
Porsche 911 Engine Upgrade when installed on the test vehicle did not affect the vehicle‘s
ability to perform its OBD I 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.

THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION,
ACCREDITATION, APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE
AIR RESOURCES BOARD OF ANY CLAIMS OF THE APPLICANT CONCERNING
ANTI—POLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF THE
PORSCHE 911 ENGINE UPGRADE.

No claim 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.

Executed at El Monte, California, this      A !   *   day of December 2015.
