 adversely affect the performance of a vehicle‘s pollution control system shall invalidate this Executive Order.

 emissions with the Doug Thorley Headers installed on various vehicles met their applicable emission standard
 during a Cold Start CVS—75 Federal Test Procedure.

   APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE AIR RESOURCES BOARD OF
   CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY ALLEGED
./ BENEFITS OF DOUG THORLEY®‘S EXHAUST HEADERS.
