     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 2639 Saddle Avenue, Oxnard,   California

93030, has requested an exemption for Borla Performance Industries‘ Ford

Stainless Steel Header Systems from the prohibitions of Section 27156 of the

California Vehicle Code.     The exemption is requested for installation on

1987—1993 model—year Ford Motor Co. heavy—duty trucks equipped with a 460

II.     CONCLUSION

       Based on emission test results performed by Borla Performance

Industries at an independent laboratory, the staff concludes that Borla

Performance Industries‘ Ford Stainless Steel Header Systems will not

adversely 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—1 allowing the installation of their Ford Stainless

Steel Header Systems on 1987—1993 model—year Ford Motor Co. heavy—duty

trucks equipped with a 460 CID multipoint fuel injected engine and 1990—1992

model—year Ford Ranger and Explorer and Mazda Navaho equipped with a 4.0

liter V6 engine.

IV.    FORD STAINLESS STEEL HEADER SYSTEMS DESCRIPTION

       The Borla Performance Industries Ford Stainless Steel Header Systems

are specifically designed for installation on 1987—1993 model—year Ford

                                      —1—


Motor Co.    heavy—duty trucks equipped with a 460 CID multipoint fuel injected

engine and 1990—1992 model—year Ford Ranger and Explorer and Mazda Navaho

equipped with a 4.0 liter V6 engine.     The header system consists of exhaust

manifolds and pre—catalyst piping.     As with the original equipment

manufacturer‘s (OEM) exhaust system, the function of the 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 Ford Stainless Steel

Header Systems feature tubular exhaust primary pipes of 1—3/4" outside

diameter for the 460 system and 1 1/2" outside diameter pipes for the 4.0

liter system.     All 460 system primary tubes on each side join to a 2—1/2"

diameter collector tube feeding into the precatalyst tubing.     The 4.0 liter

system tubes join into a 2" diameter collector tube.     The precatalyst

tubing, or ¥—pipe,    is constructed of collector sized tubing and connects to

the catalyst.     The oxygen sensor is located in the Y—pipe just before the

catalyst.    All tubes are comprised of 304 stainless steel.

     Welded just before the collector in each primary tube are the Torque

Increasing Venturis.     The manufacturer claims Torque Increasing Venturis

cause sufficient backpressure, thereby,    enhancing the EGR operation.

     The Ford Stainless Steel 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 Ford

Stainless Steel Header System which optimizes the exhaust gas flow

characteristics.     The manufacturer claims Ford Stainless Steel Header

Systems are 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

 fuel injection and emission control systems already certified with the stock

 engines.     The installation of the Ford Stainless Steel Header Systems 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 FORD STAINLESS STEEL HEADER SYSTEMS

      Borla Performance Industries requested an exemption for the

 installation of Ford Stainless Steel Header Systems on 1987—1993 model—year

 Ford Motor Co. heavy—duty trucks equipped with a 460 CID multipoint fuel

 injected engine and 1990—1992 model—year Ford Ranger and Explorer and Mazda

 Navaho equipped with a 4.0 liter V6 engine.          To evaluate the emission impact

 of the Ford Stainless Steel Header Systems on these vehicles,            the staff

 required Borla Performance Industries to test a 1992 Ford F250 heavy—duty

 truck equipped with a 460 CID engine in accordance with CVS—75 Federal Test

 Procedure (FTP).    Testing consisted of one CVS—75 FTP with vehicle in stock

 {baseline} configuration followed by one CVS—75 FTP with the header system

 installed.    Table 1 shows emission test results conducted at Milton Roy

Company, Orange, California, on the 460 CID truck.


                                     Table 1

              CVs—75 Tests Conducted by Borla Performance Industries

                                   THC         NMOG    co     NOx   g/m

       Baseline                    0.874 0.652   9.166  7.174
       Header Installed            0.884 O.685   8.841 7.830
       Difference                 +0.010 +0.033 —0.325 +0.656


      The differences between the device emission test results and baseline

emission test results submitted by the applicant were within the allowed

limits of 10% of baseline for HC,    15% of baseline for CO and 10% of baseline

                                         —3—


for NOx as specified in the "Procedures for Exemption of Add—On and Modified

Parts."   Therefore, the installation of Borla Performance Industries‘ Ford

Stainless Steel Header System did not have an adverse effect on exhaust

emissions on the test vehicle.

     Borla Performance Industries submitted all required information and

fulfilled all requirements for exemption.
