EVALUATION OF PACESETTER MARKETING, INC.‘S SHORTY HEADERS FOR AN EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS L INTRODUCTION Pacesetter Marketing, Inc. of 4433 West Van Buren #3, Phoenix, Arizona 85043 has applied for an exemption from the prohibitions in Section 27156 of the California Vehicle Code (VC) for their Shorty Headers designed for 1988—97 5.71 and 1996/97 4.3L General Motors trucks. IL CONCLUSIONS Based on submitted emissions test data of the Shorty Headers, the staff concludes that Pacesetter Marketing, Inc.‘s Shorty Headers will not adversely affect exhaust emissions from the vehicles for which the exemptionis requested. III. RECOMMENDATION The staff recommends that Pacesetter Marketing, Inc. be granted an exemption for their Shorty Headers for installation on those applicable vehicles. The staff also recommends that Executive Order D—439 be issued. IV. HEADERS The Shorty Headers are designed for installation on 1988—97 5.7L and 1996/97 4.3L General Motors trucks. The purpose of the device is to increase the vehicle‘s performance and power output by allowing more air to flow out of the engine‘s combustion chamber with less restrictions. The original exhaust manifold is a one piece cast iron manifold with variable port and chamber diameters. The manufacturer claims the tube diameter of the header is constant with no bottlenecks to create back pressure; thereby enhancing exhaust flow. All other characteristics of the OEM manifold are similar including the mounting to the stock connecting pipes. The header operates in conjunction with the OEM emission control systems already certified with the stock engine. The Shorty Headers do not defeat any emission control devices required by the manufacturer nor does it alter or circumvent the vehicle‘s On—Board Diagnostic II system or tune—up specifications.

v. THE A 1996 Chevrolet C1500 truck with a 5.7 liter engine was used for the evaluation of the header. The dynamometer inertia weight and loading were 5500 Ibs, and 14.2 hp. respectively. Emissions testing was conducted by Northern California Diagnostic Laboratory (NCDL), Napa, California. Emissions testing conducted by NCDL consisted of one Cold—Start CVS—75 Federal Test Procedure in the modified (Shorty Headers installed) configuration. The Air Resources Board did not perform tests to confirm the test results submitted by the applicant. A summary ofthe test results is shown below: Exhaust Emissions Test Results —OmaA997—Chorrolet—Camuse Mode NMHC _CO NQOx Standard 0.32 4.4 0.7 Device w/ dfs 0.20 3.0 0.4 Results from the emission tests conducted at NCDL show the vehicle emissions with the Shorty Headers installed with deterioration factors applied to be withim the vehicle‘s emission standards. Based on the test results, the staff concludes that the installation of the Pacesetter Marketing, Inc.‘s Shorty Headers will not have an adverse effect on exhaust emissions ofthe affected vehicles. The evaluation ofthe Shorty Headers on the vehicle‘s OBD II system was conducted by NCDL. NCDL indicated that a scan test displayed the vehicle‘s readiness monitors as complete and that no diagnostic trouble code were present.. An ARB staff from In—use Compliance witnessed the OBD II test at NCDL. Pacesetter Marketing, Inc. has submitted all the required information and fulfilled the requirements for an exemption.
