EVALUATION OF BORLA PERFORMANCE INDUSTRIES CHEVROLET/GMC EXHAUST 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 5901 Edison Drive, Oxnard, California 93033, has applied for an exemption from the prohibitions of Vehicle Code Section (VC) 27156 for the vehicles listed in the Appendix. Borla Performance Industries has submitted a completed application and all the required information, as well as exhaust emissions test data performed at the Air Resources Board laboratory on a 1997 5.7L Chevrolet Suburban truck. II. CONCLUSIONS Based on the submitted information and the results from comparative exhaust emissions tests performed at the Air Resources Board laboratory, the staff has determined that Borla Performance Industries‘s Chevrolet/GMC Exhaust Headers will not have any adverse effects on the exhaust emissions from vehicles for which the exemption is requested. III. RECOMMENDATION The staff recommends that Borla Performance Indfistries be granted an exemption from the prohibitions in California Vehicle Code Section 27156 for those vehicles listed in Appendix 1 and that Executive Order D—276—6 issued. IV. DEVICE DESCRIPTION The Borla Chevrolet/GMC Exhaust Headers are designed for installation on the vehicles listed in the Appendix. The exhaust manifold system operates in conjunction with the original equipment manufacturer‘s (OEM) computer controlled fuel injected system and emission control systems.

The purpose of modifying the exhaust system of the engine is to improve engine performance throughout the R.P.M. range. As with the original equipment manufacturer‘s (OEM) exhaust system, Borla Performance Industries‘ Chevrolet/GMC Exhaust Header systems, routes exhaust gases from the engine into the catalytic converter. The manufacturer states that by extracting exhaust gases more efficiently, fuel economy will also improve. The Chevrolet/GMC Exhaust Header systems are manufactured using T—304 stainless steel tubing. The Exhaust Header systems utilize Borla‘s proprietary V—8 engine header design, with the exception of the Exhaust Header system designed for the 4.3 liter Chevy/GMC S10/§15/Blazer/Jimmy/1500 series light duty trucks and the 4.8 liter in—line six cylinder GMC P1000, which utilize a tri—y design (6 into 2 into 1). The systems include all installation hardware and pre—catalyst tubing. Installation instructions are shown in the Appendix. Installation of Borla Performance Industries‘ Chevrolet/GMC Exhaust Header systems does not alter the OEM location of the oxygen sensor and the catalyst. The tune—up specifications also are unaltered from OEM specifications. V. DISCUSSION A 1997 Chevrolet Suburban equipped with a 5.7 liter fuel injected engine was used for the evaluation of the Chevrolet/G@MC Exhaust Header system. The exhaust emission tests were performed at the Air Resources Board laboratory. Testing consisted of the CVS—75 Federal Test Procedure (FTP) in the baseline (OEM) configuration followed by the CVS—75 FTP in the modified (headers installed) configuration. A summary of the test results are shown below:

Air Resources Laboratory (Based on Cold—Start CVS—75 FTP) On a 1997 Chevrolet Suburban with a 5.7L Engine Exhaust Emission Test Results {gm/mi) Non—Methane Carbon Nitrogen Hydrocarbons Monoxide Oxides Baseline 1 0.212 2.202 0.189 Baseline 2 0.238 2.534 0.164 Baseline 3 0.218 2.507 0.153 Headers 1 0.169 2.115 0.272 Headers 2 0.184 2.248 0.252 Baseline Average 0.223 2.414 0.169 Headers Average 0.177 2.182 0 .262 Difference —0.046 —0.232 +0 .093 The test results from the exhaust emission tests show that the vehicles emissions with the Borla Chevrolet/GMC Exhaust headers installed comply with the procedures for "Exemption of Add—On and Modified Parts". The staff concludes that the installation of the Borla Chevrolet/GMC Exhaust Headers will not have an adverse effect on exhaust emissions on the vehicles for which the exemption is requested. Bbr]a Performance Industries has submitted all the required information and fuifilled the requirements for an exemption.
