EVALUATION OF GREDDY PERFORMANCE PRODUCTS, INC.‘S GREDDY EXHAUST MANIFOLD FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS ie I. INTRODUCTION Greddy Performance Products, Inc. of 9 Vanderbilt, Irvine, California 92618, has applied for an exemption from the prohibitions of Vehicle Code Section (VC) 27156 for the vehicles listed in the Appendix. Greddy Performance Products, Inc. has submitted a completed application and all the required information, as well as exhaust emissions test data from a 1998 1.6L Honda Civic which was tested at California Environmental Engineering (CEE), Santa Ana, Californta. II. CONCLUSIONS Based on the submitted information and the results from exhaust emissions tests performed at CEE, the staff has determined that Greddy Performance Products,;, Inc.‘s Exhaust Manifold will not have any adverse effects on the exhaust emissions from vehicles for which the exemption is requested. III. RECOMMENDATION The staff recommends that Greddy Performance Products, Inc. be granted an exemption from the prohibitions in California Vehicle Code Section 27156 for those vehicles listed in the Appendix and that Executive Order D—397—4 be issued. IV. DEVICE DESCRIPTION The Greddy Performance Products, Inc. Exhaust Manifold is designed for installation on the vehicles listed in the Appendix. The exhaust manifold operates in conjunction with the original equipment manufacturer‘s (OEM) computer controlled fuel injected system and emission control systems already certified with the stock engine. —1—

The purpose of modifying the exhaust systém of the engine is to improve engine performance throughout the R.P.M. range which results in increased power, performance and fuel economy. As with the original equipment manufacturer‘s (OEM) exhaust system, Greddy Performance Products, Inc.‘s Exhaust Manifold, routes exhaust gases from the engine into the catalytic converter. The Greddy Performance Products, Inc.‘s exhaust manifold has a 4—into—2—into—1 configuration (four primary tubes merged with, two secondary tubes which then combine into a 2.0 inch collector pipe). It is manufactured using a 16 gauge stainless steel, with primary and secondary tube diameters of 1 3/4 inch. The 2.0 inch collector pipe fits directly onto the catalytic converter. The installation of the Greddy Exhaust Manifold alters the OEM location of the oxygen sensor on some Honda models. The oxygen sensor is located downstream of the original location to retain monitoring all four exhaust ports at the collector in the same manner as the OEM. An OEM quality wiring harness is provided by Greddy Performance Products, Inc. to accommodate the re—location of the oxygen sensor. The manifolds include all installation hardware and pre—catalyst tubing. The tune—up specifications are unaltered from OEM specifications. V. DISCUSSION A 1998 Honda Civic equipped with a 1.6 liter fuel injected engine was used for the evaluation of the exhaust manifolds. The exhaust emission tests were performed at the California Environmental Engineering laboratory. The testing consisted of the CVS—75 Federal Test Procedure (FTP) in the modified (headers installed) configuration against the emission standards. A summary of the test results are shown below: Lonim..


California Environmental Engineering (Based on Cold—Start CVS—75 FTP) Leebes.. On a 1998 Honda Civic with a 1.6L Engine Exhaust Emission Test Results (gm/mi) Non—Methane Carbon Nitrogen Hydrocarbons Monoxide Oxides Device (g/mi) 0 .17 2.3 0.3 Standard (g/mi) 0 .25 3 .4 0.4 The test results from the exhaust emission tests show that the vehicles emission levels with the Greddy Exhaust Manifold installed meet the applicable emission standards and comply with the procedures for "Exemption of Add—On and Modified Parts". ,Additiona]]y, ARB staff evaluated the impact of the Greddy Exhaust Manifold on the On—Board Diagnostic II (OBD I1I) system. Scan tool testing confirmed that the headers did not affect the vehicle‘s ability to perform OBD II system operations. The staff concludes that the installation of the Greddy Exhaust Manifold will not have an adverse effect on exhaust emissions on the vehicles for which the exemption is requested. Greddy Performance Products, Inc. has submitted all the required information and fulfilled the requirements for an exemption.
