State of California AIR RESOURCES BOARD EVALUATION OF EDELBROCK CORPORATION‘S TUBULAR EXHAUST SYSTEM FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS by Mobile Source Division State of California Air Resources Board 9528 Telstar Avenue El Monte, CA 91731—2990 (This report has been reviewed by the staff of the California Air Resources Board and approved for publication. Approval does not signify that the contents necessarily reflect the views and policies of the Air Resources Board, nor does the mention of trade names or commercial products constitute endorsement or recommendation for use.)

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.

EVALUATION OF EDELBROCK CORPORATION‘S TUBULAR EXHAUST SYSTEM FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS I. INTRODUCTION 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 Edelbrockfs 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 the 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 applicatiofl. Edelbrock claims no changes to the installation instructions or tune—up specifications are necessary for those vehicle applications requested in the update. II. CONCLUSTON Based on an engineering evaluation along with emission test results performed by Edelbrock at an independent laboratory, the staff concludes that Edelbrock‘s TES, for applications shown in Appendix A will not 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: Table 1 CVs—75 Tests Conducted on a 1989 Ford Mustang at an independent laboratory NMEC co NOx . (gm/mi) (gm/mi) (gm/mi) Baseline 0.617 1.745 0.903 Device . 0. 481 1.157 0.856 Difference 0.136 — 0.588 0.047 % 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.
