SUMMARY Edelbrock Corp. (Edelbrock) of 2700 California St., Torrance, California 90503, has requeséed to update Executive Orders D—215 which exempts Edelbrock‘s Tubular Exhaust System (TES) from the prohibitions of Vehicle Code Section 27156 of the California Vehicle Code. The existing Executive Order D—215 exempts Edelbrock‘s TES for installation on 1987—91 General Motors trucks with either a 5.0 or 5.7 liter electronic fuel injected (EFI) or throttle body injection (TBI) engine. The update is requested to include 1992 model—year General Motors trucks with either a 5.0 or 5.7 liter electronic fuel injected (EFI) or throttle body injection (TBI) engine. Edelbrock aléo requested that 1983—92 General Motors vehicles with either a 4.3, 5.0, 5.7 or 7.4 liter BFI, TBI, or carburated engine be includéd in the exemption (see appendix A for applications}. Based.on an enginsering evaluation along with emission test results performed by Edelbrock at an independent laboratory, and that the 1992 vehicles for which thé exemption update is requested are carry—overs from the model—years for which an exemption has been granted, the staff concludes that Edelbrock‘s TES will not adversely affect exhaust emission from the vehicles for which an exemption is requested. The staff recommends that Edelbrock be granted Executive Order D—215—1 allowing the installation of their TES on those applicable 1983—92 Generai Motors vehicles with either a 4.3, 5.0, 5.7 or 7.4 liter EFI, TBI, or carburated engine,.

EVALUATION OF EDELBROCK CORP.‘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 Corp. (Edelbrock) of 2700 California St., Torrance, California $0503, has requested to update Executive brders D~215 which exempts Edelbrock‘s Tubular Exhaust System (TRS) from the prohibitions of Vehicle Code Section 27156 of the California Vehicle Code. The existing Executive Order D~215 exempts Edelbrock‘s TES for installation on 1987—91 General Motors trucks with either a 5.0 or 5.7 liter electronic fuel injected (EFI) or throttle body injection (TBI) engine. The update is requested to include 1992 model—year General Motors trucks with either a 5.0 or 5.7 liter electronic fuel injected (EFI) or throttle body injection (TBI) engine. Edelbrock also requested that 1983—92 General Motors vehicles with either a 4.3, 5.0, 5.7 or 7.4 liter EFI, TBI, or carburated engine be included in the exemption (see appendix A for applications). Edelbrock claims no changes to the installation instructions or tune—up specifications are necessary for use of the TRS on the 1992 updates. II. CONCLUSION Based on an engineering evaluation along with emission test results performed by Edelbrock at an independent laboratory, and that the 1992 vehicles for which the exemption update is requested are carry—overs from the model—years for which an exemption has been granted, the staff concludes that Edelbrock‘s TES will not adversely affect exhaust emission from the vehicles for which an exemption is requested.

III. RECOMMENDATION The staff recommends that Edelbrock be granted Executive Order D—215—1 allowing the installation of }heir TES on those applicable 1983—92 General Motors vehicles with either a 4.3, 5.0, 5.7 or 7.4 liter EFI, TBI, or carburated engine (seé Appendix A). IV. TUBULAR EXHAUST SYSTEM DESCRIPTION The Edelbrock TEé is specifically designed for installation on those applicable General Motors vehicles with either a 4.3, §5.0, 5.7 or 7.4 liter EFI, TBI, or carburated engine. The TES consists of exhaust manifolds and pre—catalyst piping. As with the original equipment manufacturer‘s (OEM) exhaust system, the fqnction of Edelbrock‘s TES is to route exhaust gases from the two exhaust manifolds of the engine into a common pipe which then feeds éo the catalytic converter. Edelbrock‘s family of TES equipment share the same cémmon features: all have the same tubular exhaust flange configuration and thickness, their manifold assemblies are all designed using dual diameter pgimary pipe components, and the TES intake heat stoves are of the same configuration and dimensions. The tubular exhaust primary pipes have 1~1/2" and 1—5/8" outside diameters. The primary tube diameter on the 4.3 liter engine is 1—5/8" on cylinders 2, 4 and 6, and 1—1/2" on cylinders 1, 3 and 5. The 5.0 and 5.7 liter engines have a primary tube diameter of 1—1/2" on cylinders 1, 4, 6 and 7, and 1—5/8" on cylinders 2, 3, 5 and 8. The primary tube diameter on the 7.4 liter engine is 1—7/8" on cylinders 2, 3, 5 and:8, and 1—3/4" on cylinders 1, 4, 6 and 7. All the exhaust gases are then routed into a 2—1/4" diameter tube for the 4.3 liter and 2—1/2" diameter tube for the 5.0, 5.7 and 7.4 liter which feeds into the precatalyst piping. All tubes are comprised of #16 gage steel. —2—

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 design dimensions of fhe TES which optimizes the flow characteristics of the exhaust gases. The manufacturer claims TES was designed to improve the flow of exhaust gases from the cylinder heads to the catalytic converter, therefiy promoting improved volumetric and combustion efficiency. ‘ The system operates in conjunction with the OEM computer controlled electronic fuel injection and emission control systems already certified with the stock engines. The TES models are available both for vehicles with A.I.R. and without A.I.R. emission control system. The installation of the TES is dore by fitting only and requires no welding, modifications or adjustments to the emission control system of the affected vehicles (see Appendix B). Edelbrock supplies complete installation kits, including bolts, flafiges, washe;s, and gaskets. - v. DISCUSSTON OF THE TUBULAR EXHAUST‘.SYSTEM Edelbrock has requested an update to their Executive Orders D—215 to allow the use of the TES on the applicable 1992 model—year vehicles. Their Tubular Exhaust Systems are identical to those previously approved for the 1987—91 trucks. The staff compared the engine design of the 1991 and 1992 model—year trucks. Since the 1992 model—year trucks certified for California sales were carried—over from the 1991 model—year, no additional exhaust emission tests were required or performed. Edelbrock also requested the exemption to cover installation of TES on 4.3 liter trucks, 5.0 and 5.7 liter passenger cars and 7.4 liter trucks as listed in Appendix A.. To evaluate the emission impact of the TES on these vehicles, the staff used prior CVS~75 emission data as well as require Edelbrock to test a 1991 GM 7.4 liter Silverado truck to determine the —3—

emission impact of the TES on bigger engines. Table 1 shows emission test results conducted at Milton Roy Company, Orange, CA on a 7.4 liter truck and previous emission test results conducted on a 5.7 liter truck. Table 1 CVS—75 Tests Conducted by Edelbrock Engine Size Vehicle Tested (AC co NOx) g/m {liter) Device 7.4 91 GM Silverado .831 8.497 4.925 Baseline Full Size Truck .820 §.443 4.65 Difference +.01l +.054 +.275 Device 5.7 89 GM K1500 .481 4.789 .519 Baseline Full Size Truck .486 4.506 .555 Difference ' —.005 +.283 ~.036 Based on the emi;sion test results, it appears that the TES affects vehicle emission the most when installed on bigger engine sizes. The biggest engine size tested was a 7.4 liter GM truck, but the emission increase due to the use of the TES is within the allowable increase of 10 percent or O.1 g/mi HC, 15 percent or 1.0 g/mi CO, and 10 percent or 0.1 g/mi NOx above the baseline as specified under the "Procedures for Exemption of Add—On or Modified Parts." The additional vehicle applications requested by Edelbrock are within the range of the two worst case test vehicles. Therefore, staff concludes that based on the two vehicles that Edelbrock has tested, no emission impact would be observed on those applicable 4.3, 5.0, 5.7 and 7.4 liter engines when the TRS is installed. The staff recommends that Edelbrock be granted Executive Order D—215—1 allowing the installation of their TES on those applicable 1983—92 General Motors vehicles with}either a 4.3, 5.0, 5.7 or 7.4 liter EFI, TBI, or carburated engine (sée appendix A for applications}. ~4~
