                                     SUMMARY



         Borla Performance Industries of 5901 Edison Drive, Oxnard,

California 93033, has applied for exemption from the prohibitions in Section

27156 of the California Vehicle Code for the Chevrolet/GMC Exhaust Header

Systems listed in the Appendix .

         Borla Performance Industries has submitted a complete application

with all the required information.     Based on the results from exhaust

emission tests performed at the Air Resources Board laboratory on a 1997

Chevrolet Suburban, the staff concludes that Borla Performance Industries‘

Chevrolet/GMC Exhausts Header Systems will not adversely affect exhaust

emissions from vehicles for which an exemption is requested.

         The staff recommends that Borla Performance Industries be granted an

exemption from the prohibitions in Vehicle Code Section 27156 and that

Executive Order D—276—6 be issued.

                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:

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.
