                                   State of California
                               AIR RESOURCES BOARD

                              EXECUTIVE ORDER D-637 -3

                      Relating to Exemptions Under Section 27156
                              of the California Vehicle Code

                                    CT-Engineering
                              Performance Header System

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 Performance Header
System , manufactured and marketed by CT-Engineering of 3239 Monier Circle, Suite 5,
Rancho Cordova , California 95742 has been found not to reduce the effectiveness of
the applicable vehicle pollution control system and, therefore, is exempt from the
prohibitions of Section 27156 of the Vehicle Code for the 1991 through 2011 model year
Honda Motor Corporation vehicles listed in Exhibit A (attached). Vehicles originally
equipped with a close coupled catalyst are excluded .

For the RSX and Civic (2002 through 2011 model years only) models listed in Exhibit A ,
the Performance Header System are made up of a one-piece, short tube style header
manufactured out of 16 gauge stainless steel tubing. Individual cylinder tubes transfer
the exhaust gases into a collector tube. For all other vehicle models in Exhibit A, the
Performance Header System is made up of a short tube style header and connecting Y
pipe manufactured out of 16 gauge stainless steel tubing . In both cases, the location(s)
of the oxygen sensor(s) are unchanged from the original stock configuration . On
vehicles where the existing oxygen sensor wire loom does not reach the new oxygen
sensor location, CT-Engineering will provide a wire loom extension that will plug into the
factory connector.

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

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


                                             -2-




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

Marketing of the Performance Header System using any identification other than that
shown in this Executive Order or marketing of the Performance Header System for an
application other than those listed in this Executive Order shall be prohibited unless
prior approval is obtained from the Air Resources Board . Exemption of the
Performance Header System shall not be construed as exemption to sell, offer for sale,
or advertise any component of the kit as an individual device.

This Executive Order does not constitute any opinion as to the effect the use of the
Performance Header System may have on any warranty either expressed or implied by
the vehicle manufacturer.

This Executive Order is granted based on carryover of the following submitted
emissions test data on a 2002 RSX Type-S certified to the Low Emission Vehicle II Low
Emission Vehicle (LEV II LEV) emission standards:

Cold Start CVS-75 Federal Test Procedure

                   NMOG        co       NOx        HCHO

Standards          0.075       3.4      0.05       0.015
Device w/DFs       0.046       1.1      0.03       0.001


Supplemental Federal Test Procedure (SFTP US06 Cycle Only)

                   NMHC+NOx            CO

Standards              0.14            8.0
Device                 0.02            1.6


Test results showed that tailpipe emissions with the Performance Header System
installed on the vehicle met the vehicle's applicable emission standards during the Cold
Start CVS-75 Federal Test Procedure and the SFTP US06 cycle. This Executive Order
is also based on an examination of the On-Board Diagnostic II (OBD II) system of the
vehicle in the modified configuration. Test data showed that the Performance Header
System , when installed on the vehicle, did not affect the vehicle's ability to perform its
OBD II monitoring .

In addition to the foregoing, 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
PERFORMANCE HEADER SYSTEM.

with respect to the action taken herein in any advertising or other oral or written
communication.
