                                   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.

                 TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS

I.      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:

Difference



          Results from the emission fest show the test vehicle emissions with the L
& L Products Headers installed are within the allowable increase of 10 percent

or 0.1 gm/mile HC, 15 percent or 1.0 gm/mile CO and 10 pefcent or 0.1 gm/mile

NOx above the baseline as specified under the "Procedures for Exemption of Add—
On or Modified Parts."      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.
