                                        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.

              SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS



    I.      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

    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.
