                       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—45—199;

IT IS ORDERED AND RESOLVED: That the installation of the Racing Beat exhaust
header, produced and marketed by Racing Beat, 4789 East Wesley Drive, Anaheim,
California 92807, 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 1990—19993 (1.6 L) and 1994—19997 (1.8 L
Mazda Miata.

       1994—19997 (1.8 L)           56001                  56011

This Executive Order is valid provided that the installation instructions for the Racing
Beat 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 Racing Beat 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 Racing Beat exhaust header advertised,
offered for sale, sold with, or installed on, a motor vehicle prior to or concurrent with
transtfer to an ultimate purchaser.


  RACING BEAT                                           —     EXECUTIVE ORDER D—450—2
  RACING BEAT EXHAUST HEADER                                  (Page 2 of 3)

— This Executive Order does not constitute any opinion as to the effect the use of the
  Racing Beat exhaust header 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 and examination of
  the On—Board Diagnostic II (OBD II) system. A 1997 model—year Mazda Miata equipped
  with a 1.8 L fuel injected engine (VTK1.8VJGKEK, Tier—1, PC) was used for the
  evaluation of the Racing Beat exhaust header. Results from emissions testing
  conducted at Automotive Testing and Development Services are shown below (in
  grams per mile):

                         50k      NMHC           CO         NOx
                   Emission Level 0.204         11342       0.222
                   (w. DF applied)
                          STD        0.25       3.4         0.4

                        100k       NMHC          CO         NOx
                   Emission Level 0.215         1.437       0.222
                   (w. DF applied)
                         STD       0.310        4.2

 The emission test results in the modified configuration were below the applicable
 certification standards with the deterioration factors applied. Examination of the OBD 11
 system showed the Racing Beat exhaust header does not affect OBD 11 operation.
 Therefore, based on the test results, the staff concludes that the Racing Beat exhaust
 header meets the criteria for exempting general criteria parts. However, the ARB finds
 that reasonable grounds exist to believe that use of the Racing Beat exhaust header
 may adversely affect emissions of motor vehicles when operating under conditions
 outside the parameters of the CVS—75 Federal Test Procedure. Accordingly, the ARB
 reserves the right to conduct additional emission tests, in the future, as such tests are
 developed, that will more adequately measure emissions from all cycle phases. If such
 test results demonstrate that the Racing Beat exhaust header adversely affects
 emissions during off—cycle conditions (defined as those conditions which are beyond the
 . parameters of the Cold—Start CVS—75 Federal Test Procedure), this Executive Order
  shall be effectively rescinded as of the date the test results are validated. Further, if
  such test results or other evidence provides the ARB with reason to suspect that the
  Racing Beat exhaust header will affect the durability of the emission control system,
 Racing Beat shall be required to submit durability data to show that the durability of the
 vehicle emission control system is not, in fact, affected and/or that the add—on or
  modified part demonstrates adequate durability.

RACING BEAT EXHAUST HEADER                         |       (Page 3 of 3)            '

In addition to the foregoing, 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.

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 RACING BEAT‘S
RACING BEAT EXHAUST HEADELR.

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 revokedonly 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 after
hearing that grounds for revocation exist.

Executed at El Monte, California, this   (;    day of September 2000.
