                              EXECUTIVE ORDER D—778

                     Relating to Exemptions Under Section 27156

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 Diesel Down Pipes,
manufactured and marketed by Diamond Eye Performance, 107 West Main, Athena,
Oregon 97813, 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 the following 1994.5 to 2010 model year pickups
equipped with a diesel engine:

Part Number                       Application
122004 or 162004                  1994.5 to 1997 Ford 7.3L (2 pipes)
125102 or 165102                  2008 to 2010 Ford 6.4L (2 pipes)
     321055                       2001 to 2004 (non—catalyst) GM 6.6L (1 pipe)
     321056                       2004 to 2010 GM 6.6L (1 pipe)

The Diesel Down Pipes is a direct fit down pipe that is attached to the exhaust output
of the stock turbocharger and the vehicle‘s underfloor exhaust system. The stock
down pipe and the Diesel Down Pipes share the same construction material, metal
gage, interior volume, length, and port size. The Diesel Down Pipes has no
mechanical or electrical user adjustments. No changes are made to any
component of the stock engine for installation, including engine calibration,
turbocharger, or any other component of the exhaust system.

This Executive Order is valid provided that the installation instructions for the Diesel
Down Pipes 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 Diesel Down Pipes 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 Diesel Down Pipes using any identification other than that shown in
this Executive Order or marketing of the Diesel Down Pipes 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 the use of the
Diesel Down Pipes may have on any warranty either expressed or implied by the
vehicle manufacturer.

This Executive Order is granted based on an engineering evaluation and information
supplied by Diamond Eye Performance on the Diesel Down Pipes. Comparisons made
between the stock and modified part demonstrated similarity in material type, port size,
and basic design.

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 DIESEL DOWN
PIPES.

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    ég m day of June 2016.
