                       CALIFORNIA CODE OF REGULATIONS SECTION 2222(h)


I.          INTRODUCTION

            Car Sound Exhaust System,        Inc.           (Car Sound)    of 22961 Arroyo Vista, Rancho

Santa Margarita,   California 92688,     has applied for an exemption from the prohibitions

in Vehicle Code Section 27156 for their new series 97000 aftermarket three—way plus

oxidation catalytic converter (TWC + OC) in accordance with California regulations on

new aftermarket catalytic converters.          The ceramic monolith substrates of the new

catalyst were manufactured by AlliedSignal Environmental Catalyst (ASEC).                            The new

aftermarket catalyst is intended for the following vehicle application:

Car Sound intends to market the new TWC + OC as a replacement for catalytic converters

on applicable vehicles whose manufacturers‘                   warranty has expired and the need for

replacement of the original equipment manufacturer                      (OEM)    catalytic converter has been

established and documented.        Excluded from the application are those vehicles equipped

with an On—Board Diagnostic System II         (OBD—1I1I).

II.         CONCLUSION

           The applicant has submitted all the required information,                           and based on the

applicant‘s submitted exhaust emissions test data,                      the staff concludes that the new

aftermarket catalyst meets the criteria set forth in Vehicle Code Section 27156,                            and

Title 13, California Code of Regulations,                   Section 2222(h) for the stated application.

III.       RECOMMENDATION

           Staff recommends that the exemption be granted as requested and that

Executive Order No. D—193—18 be issued, permitting the advertisement,                           sale, and

installation of the new aftermarket catalyst on applicable vehicles.

Iv.    '   DEVICE DESCRIPTION

           Car Sound‘s new aftermarket TWC + 0C is designed to use oval ceramic

monolith substrates.     The front and rear substrates are coated with palladium and

rhodium in 5:1 ratio.    Each substrate measures 4.75 inches along the major axis, 3.15

inches along the minor axis,    and.1.93 inches in length,                      and has a volume of 24.6

cubic inches.    Alumina coating was used as the washcoat for the catalyst.                          The

substrates are contained in outer 409 stainless steel shell with Fiberfrax XPE paper


or intumescent mat,        to prevent vibration and exhaust by—pass.                      The shell is sealed by

seam weld,     and bushings are attached by arc welding.                      Aluminized soft steel hgat

shield is spot—welded to the upper and bottom sides of the converter to protect

vehicle underbody from excessive heat,.and prevent materials on the ground from diréct

contact with the catalyst shell.            The catalyst may be sold as a unit with installation

instructions or may be used in customized direct fit exhaust application.                                It is also

sold with a warranty for 25,000 miles on the substrates,                         and five years or 50,000

miles on the container or shell, and the end pipes.

v.            DEVICE EVALUATION

              Car Sound submitted data from testing conducted by Automotive Testing and

Development Services        (ATDS),   Ontario,    California.           The test catalysts were aged by

AlliedSsignal Environmental Catalyst using their ARL—102                        ("RAT B") bench—aging cycle

for 53 hours.      The test catalysts were shipped directly to ATDS where the emissions

tests were conducted for three—way plus oxidation                (TWC + OC)             application using a 1989

Dodge B250 Cargo Van 5.9L at the equivalent test weight                         (ETW)    of 6,000 lbs.     Three—way

{TWC)    application tests were conducted on a 1994 Dodge Ram 2500 Pickup Truck 5.9L at

its certification ETW of 7,500 lbs.              The oxidation catalyst application tests were

conducted on a 1988        Dodge B350 Van 5.9L at the RTW of 6,000 lbs.                       Although Car Sound

elected to conduct the TWC application test at the ETW of 7,500 lbs., they were

informed, prior to start of testing that the TWC application will still be limited to

$.9L/6,000 lbs., the limits to which the catalyst was aged.                             The test vehicles for TWC

+ OC and OC applications were ballasted in order to achieve the required ETW of 6,000 |

pounds.       The test catalysts were labeled as 94AM4 and S4AA5.                        Testing consisted of

two cold—start CVS—75 with a simulator             ("dummy" catalyst),              followed by two cold—start

CVs—75 for each of the test catalysts.              The test results for the catalyst are shown

below:

The above catalyst duplicates Car Sound‘s series 94000 TWC + OC,   which was

manufactured and bench—aged by Johnson Matthey.   However,   series 97000 is manufactured

with only one half the loading of platinum on series 94000.    Although the above test

results show that series 97000 meet the minimum requirements of the California

regulations on new aftermarket catalytic converters,   the ARB wants to further

investigate whether the performance of the catalyst was solely influenced by the

washcoat technology used by AlliedSignal.   For this reason, the ARB has requested Car

Sound to conduct further testing in order to determine the role of the bench—aging

cycle.   Due to time constraints, the ARB was unable to conduct confirmatory testing on

the new series 97000 TWC + Oc.
