                              EXECUTIVE ORDER D—370—12

                        Relating to Exemptions Under Section 27156
                                   of the California Vehicle Code

                                         DC Sports —
                                      Exhaust Header

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;

T IS ORDERED AND RESOLVED: That the installation of the Exhaust Header,
produced and marketed by DC Sports of 1451 East Sixth Street, Corona, California
92879, 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 vehicles listed in Exhibit A.

The DC Sports Exhaust Header consists of a tubular exhaust manifold available in
stainless steel or ceramic coated mild steel. The headers are supplied with oxygen
sensor harness extensions in cases where the exhaust runners have been lengthened
relative to stock dimensions, requiring relocation of the oxygen sensor further
downstream in the exhaust system at the header collector.

This Executive Order is valid provided that the installation instructions for the Exhaust
Header 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 Exhaust Header, as exempt
by the Air Resources Board, which adversely affect the performance of the vehicle‘s
pollution control system shall invalidate this Executive Order.

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

Marketing of the Exhaust Header using any identification other than that shown in this
Executive Order or marketing of the Exhaust Header 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
Exhaust Header units may have on any warranty either expressed or implied by the
vehicle manufacturer.

  This Executive Order is granted based on emission test results in the modified
  configuration using the Cold—Start CVS—75 Federal Test Procedure, Supplemental
  Federal Test Procedure (USO6), and an examination of the On—Board Diagnostic II
  (OBD I1) system. A 2004 Toyota Celica GT—S with a 1.8 liter engine (4TYXVO1.8VRE,
 LEV, PC) was used for the evaluation of the Exhaust Header. Results from emissions
 testing conducted at Automotive Testing and Development Services, are shown below
  (in grams per mile):                 ’

                   STD      0.14             8.0

  The emission test results in the modified configuration were below the applicable
— certification standards. Examination of the OBD !I system showed the Exhaust Header
  does not affect OBD II operation.

  If evidence provides the ARB with reason to suspect that the Exhaust Header will affect
  the durability of emission control systems, DC Sports shall be required to submit
  durability data to show that the durability of vehicle emission control systems are not, in
  fact, affected and/or that the add—on or modified part demonstrates adequate durability.

  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 meet the standards and procedures of Title 13, California Code of
  Regulations, Section 2222, et seq.


  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

  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
                           DC SPORTS — EXHAUST HEADER — D—370—12


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 zfll             day of February 2005.
