© SUMMARY Borla Performance Industries of 2639 Saddle Avenue, Oxnard, California 93030, has requested an exemption for Borla Performance Industries‘ Chevrolet 350 Pick—up Header System from the prohibitions of Section 27156 of the California Vehicle Code. The exemption is requested for installation on 1987—91 General Motors‘ light, medium, and heavy—duty trucks with either a 5.0 or 5.7 liter throttle body injection (TBI) engines. Based on emission test results performed by Borla Performance Industries at an independent laboratory and confirmatory testing at the Air Resources Board‘s Haagen—Smit Laboratory, the staff concludes that Borla Performance Industries‘ Chevrolet 350 Pick—up Header System 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 allowing the installation of their Chevrolet 350 Pick— up Header System on those applicable 1987—92 General Motors‘ light, medium, and heavy—duty trucks with either a 5.0 or 5.7 liter TBI equipped engine.

INTRODUCTION Borla Performance Industries of 2639 Saddle Avenue, Oxnard, California 93030, has requested an exemption for Borla Performance Industries‘ Chevrolet 350 Pick—up Header System from the prohibitions of Section 27156 of the California Vehicle Code. The exemption is requested for installation on 1987—91 General Motors‘ light, medium, and heavy—duty trucks with either a 5.0 or 5.7 liter throttle body injection (TBI) engine. II. CONCLUSION Based on emission test results performed by Borla Performance Industries at an independent laboratory and confirmatory testing at the Air Resources Board‘s Haagen—Smit Laboratory, the staff concludes that Borla Performance Industries‘ Chevrolet 350 Pick—up Header System will not adverself 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 allowing the installation of their Chevrolet 350 Pick— up Header System on 1987—1992 General Motors‘ light, medium, and heavy—duty trucks equipped with a 5.0 or 5.7 liter TBI equipped engine. IV. CHEVROLET 350 PICK—UP HEADER SYSTEM DESCRIPTION The Borla Performance Industries Chevrolet 350 Pick—up Header System is specifically designed for installation on 1987—1992 model—year General Motors‘ light, medium, and heavy—duty trucks with either a 5.0 or 5.7 liter

TBI equipped engine. The Chevrolet 350 Pick—up Header System consists of exhaust manifolds and pre—catalyst piping. As with the original equipment manufacturer‘s (OEM) exhaust system, the function of Borla Performance Industries‘ Chevrolet 350 Pick—up 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 Chevrolet 350 Pick—up Header System features tubular exhaust primary pipes of 1—5/8" outside diameters. The left and right side primary tubes are 24.5 inches and 21.8 inches long respeétively. All the exhaust gases are then routed into a 2—1/4" diameter collector tube feeding into the precatalyst piping. The oxygen sensor is located in the left—side collector. The precatalyst piping, the Y¥—pipe assembly, consists of 2—1/4 inch diameter tubing connecting the left and right exhaust manifolds to a three inch diameter collector. The collector connects to the catalyst inlet. All tubes are comprised of 304 stainless steel. Positioned just before the collector, the Torque Increasing Venturis are welded. The Torque Increasing Venturis cause sufficient backpressure enhancing the EGR operation. The Chevrolet 350 Pick—up 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 Chevrolet 350 Pick—up Header System optimizes the exhaust gas flow characteristics. The manufacturer claims Chevrolet 350 Pick—up Header System is 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 throttle body fuel injection and emission control systems already certified with the stock engines. The installation of the Chevrolet 350 Pick—up Header System 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 CHEVROLET 350 PICK—UP HEADER SYSTEM Borla Performance Industries requested an exemption for the installation of Chevrolet 350 Pick—up Header System on 1987—1992 model—year General Motors‘ light, medium, and heavy—duty trucks equipped with 5.0 or 5.7 liter TBI engines. To evaluate the emission impact of the Chevrolet 350 Pick—up Header System on these vehicles, the staff required Borla Performance Industries to test a 1990 Chevrolet 1500 light—duty truck equipped with a 5.7 liter engine in accordance with CVS—75 Federal Test Procedure (FTP). Testing consisted of one CVS—75 FTP test with the header system installed to compare emission levels against applicable emission standards. Table 1 shows emission test results conducted at Milton Roy Company, Orange, California, on the 5.7 liter truck. Table 2 shows confirmatory emissions test results conducted at the Air Resources Board‘s Haagen—Smit Laboratory on the same truck. Table 1 CVS—75 Tests Conducted by Borla Performance Industries (He co NOx) g/m Test Results 0.382 2.673 0.903 Emissions Standards 0.500 9.000 1.000

Table 2 Confirmatory CVS—75 Tests Conducted by ARB (8c co NOx) g/m Test Results O.416 3.781 0.712 Emissions Standards 0.500 9.000 1.000 Based on the emission test results, it appears that the Chevrolet 350 Pick—up Header System does not cause vehicle emissions to exceed emissions standards when installed on 5.7 liter engines. Therefore, staff concludes that based on the vehicle that Borla Performance Industries has tested, no emission impact would be observed on 5.0 or 5.7 liter engines when the Chevrolet 350 Pick—up Header System is installed. The staff recommends that Borla Performance Industries be granted Executive Order D—276 allowing the installation of their Chevrolet 350 Pick— up Header System on 1987—92 General Motors‘ light, medium, and heavy—duty trucks with a 5.0 or 5.7 liter TBI engine.
