                                                   12


   This Executive Order is granted based on emission test results in the modified configuration
   using the Cold—Start CVS—75 Federal Test Procedure (FTP), Supplemental Federal Test
   Procedure (SFTP USO6), and an examination of the On—Board Diagnostic II (OBD II) system.
   Testing a 2004 model year Chevrolet C1500 with a 5.3 liter engine (4GMXT06.0187, LEV 1
   SULEV) with the Short Style Tubular Exhaust Manifolds and Cold—Air Induction Package
   installed showed emission levels to be below the applicable emission standards. Results from
   emissions testing conducted at Automobile Club of Southern California, Diamond Bar,
   California, are shown below (in grams per mile with deterioration factors applied):

                              CVS—75                             USO6
                      NMOG CO      NOx        HCHO            NMHC+NOx         CO
   Standards 50k       0.125 3.4    0.14      0.015           0.40            10.5
   With Device        0.089 1.3    0.08       0.001           0.06             0.4

   The same emissions impact is expected of the vehicles in the application when installed with the
   Short Style Tubular Exhaust Manifolds. Examination of the OBD II system showed the Short
   Style Tubular Exhaust Manifolds does not affect OBD II system operation.

   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 SHORT STYLE TUBULAR EXHAUST MANIFOLDS.

   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
