                                    State of California
                                AIR RESOURCES BOARD

                               EXECUTIVE ORDER D—757—1

                       Relating to Exemptions Under Section 27156
                                  of the California Vehicle Code

                                  Singer Vehicle Design
                           Porsche 911 Engine Upgrade 4.0L Kit

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 4.0L Kit, 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 4.0L Kit includes the following
main parts for the naturally aspirated engine: Cylinder heads, pistons, cylinders,
crankshaft, Kinsler 50 mm throttle bodies, fuel rails, high flow injectors, camshaft,
connecting rods, Porsche 997 GT3 intake manifold, 2 Car Sound 3—Way catalytic
converters, p/n 456205, a pair of 3 into 1 16 gauge headers, oil cooler, Porsche 993 Turbo
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 engine block is
retained. Overall displacement is increased from a 3.6L to a 4.0L. 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 4.0L Kit. Catalytic
converter part numbers must be visible for smog check and fuel pressure regulator cannot
be adjustable.

This Executive Order is valid provided that the installation instructions for the Porsche 911
Engine Upgrade 4.0L Kit 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
4.0L Kit, 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 new 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 prior Diurnal Heat Build + Hot Soak test data done in
support of Executive Order D—757:


                                         CVS—75 FTP
                                  HC          co    NOx
   Standards                      0.41        7.0   0.4
   Device                         0.20        3.2   0.2


   Prior Diurnal Heat Build + Hot Soak

                  HC
   Standard       2.0
   Device         0.8

Test results showed that the Porsche 911 Engine Upgrade 4.0L Kit 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 4.0L Kit 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 4.0L KIT.

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      13      day of April 2017.
