     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:

           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.
