                                      SUMMARY

     Edelbrock Corporation (Edelbrock}) of P. O. Box 2936, Torrance,

California 90509—2936, has requested to update Executive Order D—215—1 which

exempts Edelbrock‘s Tubular Exhaust System (TES)     from the prohibitions of

California Vehicle Code Section 27156.      The existing Executive Order D—215—1

exempts Edelbrock‘s TES for installation on 1982 to 1992 General Motors

vehicles with a 4.3,   5.0,   5.7 or 7.4 liter engine.   The update is requested

to reflect new part numbers added due to changes in extension pipe designs

and new material used.    Edelbrock also requested that 1986—92 Ford, Lincoln

and Mercury vehicles equipped with a 5.0 liter fuel—injected engine be

included in this exemption application.

     Based on an engineering evaluation along with emission test results

performed by Edelbrock at .an independent laboratory, the staff concludes

that Edelbrock‘s TES will not adverseiy affect exhaust emission from the

vehicles for which an exemption is requested.

     The staff recommends that Edelbrock be granted Executive Order D—215—2

allowing the installation of their TES on those vehicle applications listed

in Appendix A.

adversely affect exhaust emissions.


III.   RECOMMENDATION

       The staff recommends that Edelbrock be granted Executive Order D—215—2

allowing the installation of their TES for the part nos. and vehicle

applications listed in Appendix A.




IV.    TUBULAR EXHAUST SYSTEM DESCRIPTION

       The Edelbrock TES is an exhaust system designed to improve the gas

dynamics of engine exhaust.     It conducts exhaust gases through individual

primary tubes from the cylinder heads to 4—into—1 collector on each side of

the exhaust manifold, and then to a 2—into—1 collector which fits directly

to the catalytic converter.     The TES is functionally identical to the cast

iron exhaust manifolds and tubular steel collector;pipes of the OEM exhaust

system.     The difference is the designvdimensions of the TES which optimizes

the flow characteristics of the exhaust gases.     TES provides for connection

of all OEM emission control devices on the applicable vehicles at the

required location.      The manufacturer claims TES was designed to improve the

flow of exhaust gases from the cylinder heads to the catalytic converter,

thereby promoting improved volumetric and combustion efficiency.

       The TES models are available both for vehicles with A.I.R.    and without

A.I.R. emission control system.      The models with 7900 part number series are

treated externally with aluminum based coating to prevent corrosion.       The

installation of the TES is done by fitting only and requires no welding,

modifications or adjustments to the emission control system of the affected

vehicles.     Edelbrock supplies complete inatallation kits,   including bolts,

flanges, washers and gaskets.      Appendix A contains the part numbers and

applicable vehicles.


v.   DISCUSSION

     Edelbrock has requested an update to reflect new part numbers added due

to changes in extension pipe designs and new material used.    The new

Edelbrock TES part numbers, applicable for the 4.3 L light—duty vehicles,

the 5.0 L/5.7 L light—duty vehicles and the 5.0 L/S5.7 L Camaro/Firebird,

are required because the extension pipe attaching tfleJheader to the

catalytic converter required some minor angle changes to clear certain

chassis components.   These exhaust headers use an identical confiquration to

those previously tested by Edelbrock in support of Executive Order D—215—1.

     The new Edelbrock TES part numbers using the 6600 series number reflect

a tubing material change to a 409 series stainless steel alloy.     This same

tubing alloy is used in the original equipment manéfactuxer’s exhaust

system.   Edelbrock has deemed this magerial change is necessary on certain

vehicle applications to ensure satisfactory exhaust system warranty.

     Staff has concluded that the modifications due to the change in

extension pipe design and the change in exhaust header material do not

significantly alter the design of the previously exempted exhaust header,

and no emission impact would be observed from these changes.

     Edelbrock also requested the exemption to cover installation of TES on

1986—92 Ford, Mercury and Lincoln vehicles equipped with a 5.0 liter engine.

A 1989 Ford Mustang with a 5.0 liter (302 CID)}   fuel injected qgasoline engine

was used for the evaluation of the Tubular Exhaust System.     The dynamometer

inertia weight and loading were 3750—lbs and 10.2—hp respectively.


     Emission tests conducted by Milton Roy Company for Edelbrock consisted

of one Cold—Start CVS—75 emission test in the unmodified (baseline)

configuration and one Cold—Start CVS—75 emission test in the modified

(header system installed) confiqguration.       The ARB did not perform tests to

confirm the test results submitted by the applicant.         A summary of the test

results is shown below in Table 1:

% Difference                   —22,.0%     —33.7%      —5.2%

     The 1989 Ford Mustang emission test data did not show an increase in

exhaust emissions.   Therefore,   staff concludes that no emission impact would

be observed on 1986—92 Ford, Mercury or Lincoln vehicles equipped with 5.0

liter engines when the TES is installed.

     The staff recommends that Edelbrock be granted Executive Order D—215—2

allowing the installation of their TES for the part numbers and applications

listed in Appendix A.
