SUMMARY Borla Performance Industries of 2639 Saddle Avenue, Oxnard, California 93030, has requested an exemption for Borla Performance Industries‘ Ford Stainless Steel Header Systems from the prohibitions of Section 27156 of the California Vehicle Code. The exemption is requested for installation on 1987—1993 model—year Ford Motor Co. heavy—duty trucks equipped with a 460 ° CID multipoint fuel injected engine and 1990—1992 model—year Ford Ranger and Explorer and Mazda Navaho equipped with a 4.0 liter V6 engine. Based on emission test results performed by Borla Performance Industries at an independent laboratory, the staff concludes that Borla Performance Industries‘ Ford Stainless Steel Header Systems will not adversely affect exhaust emission from the vehicles for which an exemption is requested. The staff recommends that Borla Performance Industries be granted Executive Order D—276—1 allowing the installation of their Ford Stainless Steel Header Systems on those applicable 1987—1993 model—year Ford Motor Co. heavy—duty trucks equipped with a 460 CID multipoint fuel injected engine and 1990—1992 model—year Ford Ranger and Explorer and Mazda Navaho equipped with a 4.0 liter V6 engine.

EVALUATION OF BORLA PERFORMANCE INDUSTRIES‘ FORD STAINLESS STEEL HEADER SYSTEMS FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS I. INTRODUCTION Borla Performance Industries of 2639 Saddle Avenue, Oxnard, California 93030, has requested an exemption for Borla Performance Industries‘ Ford Stainless Steel Header Systems from the prohibitions of Section 27156 of the California Vehicle Code. The exemption is requested for installation on 1987—1993 model—year Ford Motor Co. heavy—duty trucks equipped with a 460 CID multipoint fuel injected engine and 1990—1992 model—year Ford Ranger and Explorer and Mazda Navaho equipped with a 4.0 liter V6 engine. II. CONCLUSION Based on emission test results performed by Borla Performance Industries at an independent laboratory, the staff concludes that Borla Performance Industries‘ Ford Stainless Steel Header Systems will not adversely affect exhaust emission from the vehicles for which an exemption is requested. III. RECOMMENDATION The staff recommends that Borla Performance Industries be granted Executive Order D—276—1 allowing the installation of their Ford Stainless Steel Header Systems on 1987—1993 model—year Ford Motor Co. heavy—duty trucks equipped with a 460 CID multipoint fuel injected engine and 1990—1992 model—year Ford Ranger and Explorer and Mazda Navaho equipped with a 4.0 liter V6 engine. IV. FORD STAINLESS STEEL HEADER SYSTEMS DESCRIPTION The Borla Performance Industries Ford Stainless Steel Header Systems are specifically designed for installation on 1987—1993 model—year Ford —1—

Motor Co. heavy—duty trucks equipped with a 460 CID multipoint fuel injected engine and 1990—1992 model—year Ford Ranger and Explorer and Mazda Navaho equipped with a 4.0 liter V6 engine. The header system consists of exhaust manifolds and pre—catalyst piping. As with the original equipment manufacturer‘s (OEM) exhaust system, the function of the header system is to route exhaust gases from the two exhaust manifolds of the engine into a common pipe which then feeds to the catalytic converter (see appendix for drawings). Borla Performance Industries‘ family of Ford Stainless Steel Header Systems feature tubular exhaust primary pipes of 1—3/4" outside diameter for the 460 system and 1 1/2" outside diameter pipes for the 4.0 liter system. All 460 system primary tubes on each side join to a 2—1/2" diameter collector tube feeding into the precatalyst tubing. The 4.0 liter system tubes join into a 2" diameter collector tube. The precatalyst tubing, or ¥—pipe, is constructed of collector sized tubing and connects to the catalyst. The oxygen sensor is located in the Y—pipe just before the catalyst. All tubes are comprised of 304 stainless steel. Welded just before the collector in each primary tube are the Torque Increasing Venturis. The manufacturer claims Torque Increasing Venturis cause sufficient backpressure, thereby, enhancing the EGR operation. The Ford Stainless Steel Header System is functionally identical to the cast iron exhaust manifolds and tubular steel collector pipes of the OEM exhaust system. The difference is the design dimensions of the Ford Stainless Steel Header System which optimizes the exhaust gas flow characteristics. The manufacturer claims Ford Stainless Steel Header Systems are designed to improve the flow of exhaust gases from the cylinder heads to the catalytic converter, thereby promoting improved volumetric and combustion efficiency.

The system operates in conjunction with the OEM computer controlled fuel injection and emission control systems already certified with the stock engines. The installation of the Ford Stainless Steel Header Systems is done by fitting only and requires no welding, modifications or adjustments to the emission control system. Borla Performance Industries supplies complete installation kits, including bolts, flanges, washers, and gaskets. —v. DISCUSSION OF THE FORD STAINLESS STEEL HEADER SYSTEMS Borla Performance Industries requested an exemption for the installation of Ford Stainless Steel Header Systems on 1987—1993 model—year Ford Motor Co. heavy—duty trucks equipped with a 460 CID multipoint fuel injected engine and 1990—1992 model—year Ford Ranger and Explorer and Mazda Navaho equipped with a 4.0 liter V6 engine. To evaluate the emission impact of the Ford Stainless Steel Header Systems on these vehicles, the staff required Borla Performance Industries to test a 1992 Ford F250 heavy—duty truck equipped with a 460 CID engine in accordance with CVS—75 Federal Test Procedure (FTP). Testing consisted of one CVS—75 FTP with vehicle in stock {baseline} configuration followed by one CVS—75 FTP with the header system installed. Table 1 shows emission test results conducted at Milton Roy Company, Orange, California, on the 460 CID truck. Table 1 CVs—75 Tests Conducted by Borla Performance Industries THC NMOG co NOx g/m Baseline 0.874 0.652 9.166 7.174 Header Installed 0.884 O.685 8.841 7.830 Difference +0.010 +0.033 —0.325 +0.656 The differences between the device emission test results and baseline emission test results submitted by the applicant were within the allowed limits of 10% of baseline for HC, 15% of baseline for CO and 10% of baseline —3—

for NOx as specified in the "Procedures for Exemption of Add—On and Modified Parts." Therefore, the installation of Borla Performance Industries‘ Ford Stainless Steel Header System did not have an adverse effect on exhaust emissions on the test vehicle. Borla Performance Industries submitted all required information and fulfilled all requirements for exemption.
