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 Exhaust Headers, manufactured
and marketed byDoug‘s Headers, 1391 Dodson Way, Riverside, California, 92507 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 vehicle
applications listed in Exhibit A which is attached hereto and incorporated herein. The following
vehicles that are equipped with a close coupled warm up catalyst are excluded from this
Executive Order for long tube headers only: General Motors 2001 model year vehicles
with engine test groups 1GMXA05.3185, 1GMXA06.0188, 1GMXA08.1201, and
1GMXA08.1203

The Exhaust Headers are manufactured out of 16 gage stainless steel or 14 gage mild steel.          |
The design of the long tube headers may include a Y—pipe, while that of short tube headers may              >
either connect to the stock connecting pipe or include a new one. All emission components are           i
retained in their original location. The location of the oxygen sensor is at the collector in
the connecting pipe, in the stock location and configuration.

This Executive Order is valid provided that the installation instructions for the Exhaust Headers
will not recommend tuning the vehicle to specifications different from those submitted by the       l
                                                                                                    I
device manufacturer.

This Executive Order shall not apply to any 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.

Changes made to the design or operating conditions of the Exhaust Headers, 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 Exhaust Headers using any identification other than that shown in this
Executive Order or marketing of the Exhaust Headers for an application other than those listed      .
in this Executive Order shall be prohibited unless prior approval is obtained from the Air          »4
Resources Board.

 Exemption of the Exhaust Headers 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 Exhaust
 Headers may have on any warranty either expressed or implied by the vehicle.


                                              —2—


This Executive Order is granted based on prior submitted emissions test data (Executive Orders
D—554 and D—554—2) and emissions test data generated on a 2005 model year 6.0L Chevrolet
C1500 certified to the Super Ultra Low—Emission Vehicle (SULEV) emission standards, and a
2005 model year 5.4L Ford F—150 certified to the Low—Emission Vehicle II Low—Emission Vehicle
(LEV fI LEV) emission standards. Emission levels of the modified vehicles (short tube header
installed)—met the applicable emission standards over the Cold—Start CVS—75 Federal Test
Procedure (FTP) and the Supplemental FTP (USO6) test cycles. Results are in grams permile
with deterioration factors applied to the CVS—75 FTP test results:

affect the vehicle‘s ability to perform its OBD II monitoring.
