                                   Corvette 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—45—9;

IT IS ORDERED AND RESOLVED: That the installation of the Corvette Exhaust Header,
manufactured and marketed by B&B Fabrication, Inc., 23045 North 15th Avenue, Phoenix,
Arizona 85027 has been found not to reduce the effectiveness of the applicable vehicle
pollution control system and, therefore, is exempt from the prohibitions of Section 27156 of
the Vehicle Code for 1997 through 2001 model—year Corvettes.

The Corvette Exhaust Header is manufactured out of 16 gage stainless steel. It is a shorty
design that bolits up to the stock connecting pipes. The oxygen sensor is located at the
collector of the header.

This Executive Order is valid provided the installation instructions for the Corvette Exhaust
Header will not recommend tuning the vehicle to specifications different from those of the
vehicle manufacturer.

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

Changes made to the design or operating conditions of the Corvette 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.

Marketing of the Corvette Exhaust Header using any identification other than that shown in
this Executive Order or marketing of the Corvette 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.

Exemption of the Corvette Exhaust Header shall not be construed as exemption to sell, offer
for sale, or advertise any component of the kit as an individual device.


                                                2.

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

This Executive Order is granted based on the emissions test data submitted by
B&B Fabrication, Inc. on a 2000 General Motors Corvette, certified to the Low Emission Vehicle
{(LEV) emission standards.

                  NMOG CO          NOx    HCHO
Standards         0.075 3.4       0.2     0.015
device w/ dfs     0.052 1.5       0.17    0.002

Test results showed that the Corvette Exhaust Header when installed on the vehicle did not
cause tailpipe emissions to exceed the vehicle‘s applicable emission standards during a Cold
Start CVS—75 Federal Test Procedure. This Executive Order is also based on the On Board
Diagnostic II (OBD II) testing conducted on the same test vehicle. Test data showed that the
Corvette Exhaust Header when installed on the vehicle did not affect the vehicle‘s ability to
perform OBD I! monitoring.

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 B&B FABRICATION, INC ‘S CORVETTE EXHAUST HEADER.

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.
