                              EXECU1-IVE ORDER D-411-9

                       Relating to Exemptions Under Section 27156
                                    of the Vehicle Code


                             Gibson Performance Corporation
                              Performance Exhaust Headers

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 Performance Exhaust
Headers manufactured and marketed by Gibson Performance Corporation of 1270
Webb Circle, Corona, CA 92879, 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 Vehicle Code for the 1988 through 2009 model
year General Motors trucks listed in Exhibit A.

The Performance Exhaust Headers consists of tubular, short-length exhaust
manifolds made of 16 gauge steel, and the corresponding assembly hardware. The
manifolds replace the original exhaust manifolds upstream of the stock catalytic
converters. Individual cylinder tubes transfer the exhaust gases into a collector tube.
As applicable, oxygen sensors and exhaust gas recirculation sensors are removed
from the stock manifold and installed on similar locations on the replacement
headers. All other emission-related components are in their stock location. The
header kit is available in either in chrome, stainless steel or ceramic-coated steel.

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

This Executive Order is valid provided that the installation instructions for the Ford
Exhaust Header Kit 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 devices, a s exempted by
the Air Resources Board, that adversely affect the performance of a vehicle's
pollution control system shall invalidate this Executive Order.


Marketing of these devices 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
Air Resources Board.

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

This exemption is issued based on previously submitted emissions test data from an
independent laboratory on a 2007 model year Chevrolet Silverado Truck (Test Group
7GMXT05.3380) certified to the Low Emission Vehicle II Ultra Low Emission Vehicle
(LEV II ULEV) and Supplemental Federal Test Procedure (SFTP) standards:

Device (glmi) with d f s applied               0.057        0.7      0.02

SFTP (US06 Cycle only):



Standards (glmi)
Device (glmi)


Test results showed that the Performance Exhaust Headers when installed on the
vehicle did not cause exhaust emissions to exceed the applicable emission standards
during either the Cold Start Federal Test Procedure or the SFTP US06 cycle. This
Executive Order is also based on the On-Board Diagnostic II (OBD II) testing
conducted on the same test vehicle. The Performance Exhaust Headers when
installed on the test vehicle did not affect the vehicle's ability to perform its OBD II
monitoring.

In addition, 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 mo.dified 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


  GIBSON PERFORMANCE CORPORA1-ION - PERFORMANCE EXHAUST HEADERS - D-411-9


CONCERNING ANTI-POLLLITION BENEFITS OR ANY ALLEGED BENEFITS OF
THE PERFORMANCE EXHAUST HEADERS.

No claims 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
