  manufactured and marketed by B&B Fabrication, Inc., 23045 North 15th Avenue, Phoenix,

_ groups 2GMXVO5.7082, 3GMXVO5.7082, and 4GMXV05.7082 with 206 models.

 design that bolits up to the stock connecting pipes. The oxygen sensor is located at the
 collector of the header. Part nos. FCOR—0250 is applicable to 1997 through 1999
 model—year Corvette, FCOR—0255 is applicable to 2000 model—year Corvette, and

 sale, sold with, or installed on a motor vehicle prior to or concurrent with transfer to an
 ultimate purchaser.                             v

                                                  —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 Orderis 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    017     0.002

Test results showedthat 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 l1 (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.
