State of California AIR RESOURCES BOARD EVALUATION OF THE L & L PRODUCTS‘ "ULTRA FLOW" PERFORMANCE HEADERS FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 _IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS December 1994

State of California AIR RESOURCES BOARD EVALUATION OF THE L & L PRODUCTS!‘ "ULTRA FLOW" PERFORMANCE HEADERS 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 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 mention of trade names or commercial products constitute endorsement or recommendation for use.)

SUMMARY L & L Products of 3210 Century, Rowlett, Texas, 75088, has applied for an exemption from the prohibitions in Section 27156 of the California Vehicle Code (VC) for their "Ultra Flow" Performance Headers (Headers). The Headers are designed for installation on 1967—94 model year Ford trucks equipped with either a 429 CID or 460 CID (7.5 liter) heavy—duty gasoline engines. Based on the results from emission tests performed at an independent laboratory on a 1994 Ford F—250 truck equipped with a 7.5 lTiter (460 CID) heavy— duty gasoline engine, the staff concludes that L & L Products‘ "Ultra Flow" Performance Headers will not adversely affect exhaust emissions from vehicles for which an exemption is requested.i The staff recommends that L & L Products be granted an exemption as — requested and that Executive Order D—373 be issued.

INTRODUCTION L & L Products of 3210 Century, Rowlett, Texas 75088, has applied for an exemption from the prohibitions in Section 27156 of the California Vehicle Code (VC) for their "Ultra Flow" Performance Headers (Headers). The Headers are designed for installation on 1967—94 model year Ford trucks equipped with either a 429 CID or 460 CID (7.5 liter) heavy—duty gasoline engines. L & L Products has submitted test data from a 1994 Ford F—250 truck equipped with a 7.5 lTiter heavy—duty gasoline engine tested at Roush Laboratories, Garden Grove, California. II. CONCLUSION Based on the results from emission testing performed at Roush Laboratories on a 1994 Ford F—250 truck equipped with a 7.5 liter heavy—duty gasoline engine, the staff concludes that L & L Products‘ Headers will not adversely affect exhaust emissions from vehicles for which an exemption is requested. OIIL. RECOMMENDATION The staff recommends that L & L Products be granted an exemption for their Headers for installation on 1967—94 model year Ford trucks equipped with cither a 429 CID or 460 CID (7.5 liter) heavy—duty gasoline engines. The staff also recommends that Executive Order D—373 be issued. IV. DESCRIPTION OF THE L & L PRODUCTS HEADERS The L & L_Products‘ Headers are designed for installation on 1967—94 model year Ford trucks equipped with either a 429 CID or 460 CID (7.5 liter)

heavy—duty gasoline engines. The Headers operate in conjunction with the original equipment manufacturer‘s (OEM) emission control systems. Thé purpose of modifying the exhaust system of the engine is to increase horsepower and torque throughout the R.P.M. range. As with the original equipment manufacturer‘s (OEM) exhaust system, L & L Products‘ Headers routes exhaust gases from the engine into the catalytic converter. The "Ultra Flow" Performance Headers are manufactured using either 14 gauge mild steel plated with electroless nickel or 16 gauge T—304 stainless steel tubing. The Headers utilize L & L Product;’ proprietary V—8 engine header design inc1udfng .500 inch thick header flanges. The oxygen sensor is positioned at the junction of the individual header tubes and the collector. Systems include all installation hardware and pre—catalyst tubing. Installation of L & L Products‘s Header does not alter the OEM location of the catalyst. The tune—up specifications are also unaltered from OEM specifications. v. DISCUSSION OF THE L & L PRODUCTS HEADER A 1994 Ford F—250 truck equipped with a 7.5 liter heavy—duty gasoline engine was used for the evaluation of the Header system. The emission tests conducted by Roush Laboratories for L & L Products consisted of one Cold CVS—75 Federal Test Procedure (FTP) in baseline (OEM) configuration‘and one Cold CVS—75 Federal Test Procedure (FTP) in the modified (Headers installed) configuration. The Headers used during testing were part number 79755 constructed of 16 gauge T—304 stainless steel tubing. Since this engine was originally certified using an engine dynamometer,*the vehicle dynamometer weight was calculated as 7000—1Ibs and the road load horsepower calculated as 18.2—hp. The ARB did not perform any test to confirm the test resuits submitted by the applicant. A summary of the test results is shown on next page: —2—

Therefore, based on the test results, the staff concludes that the installation of the L & L Producfs’ Headers will not have an adverse effect on exhaust emissions on the vehicles which exemption is requested. L & L Products has submitted all the required information and fulfilled the requirements for an exemption.
