                             EXECUTIVE ORDER D—455—23

                      Relating to Exemptions Under Section 27156
                                   of the Vehicle Code


                                   Comptech Machine
                                 Comptech 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—45—9;

IT IS ORDERED AND RESOLVED: That the installation of the Comptech Supercharger
manufactured and marketed by Comptech Machine of 4717 Golden Foothill Parkway, El
Dorado Hills, CA 95762 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 California Vehicle Code for 2004 and earlier Honda Motor Corporation NSX and
$2000 vehicles.

The Comptech Supercharger includes the following main components: NOVI 1000
supercharger, Comptech air intake box (S2000 only), intake manifold (NSX only), Walbro fuel
pump (S2000 only), and Comptech fuel pressure regulator. For both vehicle models, the stock
fuel pressure regulators are replaced with the higher—pressure Comptech regulator. The
$2000‘s factory fuel pump is replaced, and the stock air intake box is replaced with the kit‘s
smaller intake box in order to accommodate the supercharger. The NSX‘s stock intake
manifold is replaced with the combination supercharger and intake manifold assembly. The
stock NSX fuel pump is modified with a regulator unit to increase the voltage to it, and the
stock 15 amp fuel pump fuse is replaced with a 20 amp fuse. For 2002 and later models of
both vehicles, an optional controller may be installed in lieu of standard mechanical bypasses
and vacuum line modifications. All other emission—related components are in the stock
location relative to the throttle body. The following are the supercharger pulley specifications:
The NSX 3.2L engine uses a 3.8" diameter pulley, the NSX 3.0L engine uses a 4.2" diameter
pulley, the S$2000 2.2L engine uses a 4.5" diameter pulley, and the $2000 2.0L engine uses a
4.8" diameter pulley . Maximum boost is limited to 6 psi.

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

                                                _2


This Executive Order is valid provided that the installation instructions for the supercharger will
not recommend tuning the vehicle to specifications different from those of the vehicle
manufacturer.

Changes made to the design or operating conditions of the device, as exempted by the Air
Resources Board (ARB), that adversely affect the performance of a vehicle‘s pollution control
system shall invalidate this Executive Order.

Marketing of this device 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 ARB.

This Executive Order does not constitute any opinion as to the effect that the use of this device
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 2004 model year Honda Motor Company $2000 vehicle (Test Group
4HNXVO2.2PJE) certified to the Low Emission Vehicle (LEV) and Supplemental Federal Test
Procedure (SFTP) standards:

Test results showed that the Comptech Supercharger when installed on the vehicle did not
cause exhaust emissions to exceed the applicable emission standards during the Cold Start
CVS—75 Federal Test Procedure or SFTP cycles. This Executive Order is also based on the
On—Board Diagnostic II (OBD I1) testing conducted on the same test vehicle. Comptech
Supercharger when instalied on the testvehlcle did not affect the vehicle‘s ability to perform its
OBD I! monitoring.

In addition, the ARB 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
