*   Headers with a "step" in the primary tubes (slight increase in diameters at the end of the tubes)
*   Headers with HTC (High Tech. Coatings) metallic thermal coating

This exemption is based on an emission test conducted by Hedman Hedders on a 1996 model—year
2.2 liter Honda Accord. Hedman Hedders submitted the following Cold—Start CVS—75 Federal Test
Procedure emission results:

                                          NMOG            CO         NOx          HCHO
                                                          (grams per mile)

             With Headers                 0.072           0.720      0.128        0.001
             DF—Applied                   0.082           0.813       0.143       0.001
             50,000—Mile Standard         0.125           3.4        0.4          0.015

The test data show that the Chikara exhaust headers did not adversely affect the exhaust emissions
of the 1996 model—year Honda Accord. The same emissions impact is expected when the Chikara
exhaust headers are installed on the various Honda vehicles for which the exemption is requested.

This Executive Order is valid provided that installation instructions for the Chikara exhaust headers
not recommend tuning the vehicles to specifications different from those of the vehicle

CHIKARA EXHAUST HEADERS                                       (Page 3 of 3)

Changes made to the design or operating conditions of the Chikara exhaust headers, as exempt by
the ARB, which adversely affect the performance of the vehicles‘ pollution control system, shall
invalidate this Executive Order.

Marketing of the Chikara exhaust headers using identification other than that shown in this
Executive Order or for an application other than that listed in this Executive Order shall be
prohibited unless prior approval is obtained from the ARB. Exemption of the Chikara exhaust
headers shall not be construed as exemption to sell, offer for sale, or advertise any component of
the exhaust headers as an individual device.

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

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 Executive Order.
 The Executive Order may be revoked only after a ten—day written notice of intention to revoke the
 Executive Order, in which period the holder of the Executive Order may request in writing a
 hearing to contest the proposed revocation. If a hearing is requested, it shall be held within ten
 within ten days of receipt of the request, and the Executive Order may not be revoked until a
determination after the hearing that grounds for revocation exist.
Executed at El Monte, California, this __2@ day of August 1998.
