Pioneer Boulevard, Santa Fe Springs, California 90670—3221 has been found not to reduce the effectiveness of the applicable vehicle pollution control systems and, therefore, is exempt from the prohibitions of Section 27156 of the Vehicle Code for the truck applications listed in Exhibit A, excluding any vehicle certified to Ultra Low Emission Vehicle (ULEV) or lower emission standards. This Executive Order is valid provided that the installation instructions for Exhaust Headers will not recommend tuning the vehicle to specifications different from those of the vehicle manufacturer. This Executive Order shall not apply to any Downey Off Road Exhaust Headers advertised, offered for sale, sold with, or installed on a motor vehicle prior to or concurrent with the transfer to an ultimate purchaser. Changes made to the design or operating conditions of Exhaust Headers, 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 Exhaust Headers using any identification other than that shown in this Executive Order or marketing of the Exhaust Headersfor 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 system shall not be construed as exemption to sell, offer for sale, or advertise any component of the kit as an individual device.

This Executive Order does not constitute any opinion as to the effect that the use of the Exhaust Headers may have on any warranty either expressed or implied by the vehicle manufacturer. This Executive Order is granted based on the following submitted emissions test data on a 1999 Toyota 4Runner equipped with a 3.4 liter engine and certified to the Low Emission Vehicle (LEV) emission standard: NMOG CO NOx HCHO Standards 0.100 4.4 0.4 0.018 Device w/dfs 0.089 0.7 0.3 0.004 Test results showed that tailpipe emissions with the Exhaust Headers installed on the vehicle met the vehicle‘s emission standard during a Cold Start CVS—75 Federal Test Procedure. This Executive Order is also based on On Board Diagnostic II (OBDI!) testing conducted on the same test vehicle. Test data showed that the header when installed on the vehicle did not affect the vehicle‘s ability to perform OBDII 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 TH EAPPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF DOWNEY OFF ROAD MANUFACTURING‘S EXHAUST HEADERS.
