for sale, or advertise any component of the kit as an individual device.

Exhaust Header may have on any warranty either expressed or implied by the vehicle _
manufacturer.

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

cause tailpipe emissions to exceed the vehicle‘s applicable emission standard during a Cold
Start CVS—75 Federal Test Procedure. This Executive Order is also based on On Board
Diagnostic l1 (OBD I1) testing conducted on the same test vehicle. Test data showed that the
Corvette Exhaust Header when installed on the vehicles did not affect the vehicle‘s ability to
perform OBD l monitoring.
