(Page 1 of 2) State of California AIR RESOURCES BOARD EXECUTIVE ORDER D—167—19 Relating to Exemptions Under Section 27156 of the Vehicle Code HEDMAN HEDDERS TUBULAR EXHAUST MANIFOLD SYSTEM Pursuant to the authority vested in the Air Resources Board (ARB) by Section 27156 of the Vehicle Code; and Pursuant to the authority vested in the undersigned by Sections 39515 and 39516 of the Health and Safety Code and Executive Order G—45—9; IT IS ORDERED AND RESOLVED: That installation of the Tubular Exhaust Manifold System (TEMS), manufactured by Hedman Hedders of 9599 Jefferson Boulevard, Culver City, California 90232, has been found not to reduce the effectiveness of the applicable vehicle pollution control system, and therefore, TEMS, part nos. 89490 and 89490—6 (with HTC metallic thermal coating), is exempt from the prohibitions of Section 27156 of the Vehicle Code for installation on 1998 and 1999 model—year 4.6 liter V—8 Ford Motor Company F150 and F250 trucks, including those trucks certified to the Low—Emission Vehicle exhaust emission standards. This exemption is based on emission and on—board diagnostic (OBD II) system testing Hedman Hedders conducted on a 1999 model—year 4.6 liter V—8 Ford F150 truck with the exhaust headers. Hedman Hedders submitted the following Cold—Start CVS—75 Federal Test Procedure emission test results: NMOG CO NOx HCHO . (grams per mile) With Headers 0.054* _ 0.306 0.074 0.001* DF—Applied 0.062 0.366 0.094 0.001 Standards 0.16 4.4 0.40 0.018> * Calculated using OEM NMOG/NMHC and HCHO/NMHC ratios. The test data show that the exhaust headers did not adversely affect the exhaust emissions of the 1999 model—year Ford truck. The exhaust headers were also found to not affect the operation of the vehicle‘s OBD II system. The same results are expected when the exhaust headers are installed on the vehicles for which the exemption is requested. This Executive Order is valid provided that installation instructions for the exhaust headers not recommend tuning the vehicles to specifications different from those of the vehicle manufacturer.

This Executive Order does not constitute any opinion as to the effect the use of the exhaust headers may have on any warranty either expressed or implied by the vehicle manufacturer. No claim of any kind, such as "Approved by the Air Resources Board," may be made with respect to the action taken herein in any advertising or other oral or written cormmunication.
