                      Relating to Exemptions Under Section 27156
                                  of the Vehicle Code

                          CAR SOUND EXHAUST SYSTEM, INC.
           "THREE—WAY PLUS OXIDATION CATALYTIC CONVERTER SERIES 98000°

WHEREAS,   Vehicle Code Sections 27156 and 38391,            and Title 13,        California   Code
of Regulations (hereafter "CCR") Section 2222(h), authorize the California
Air Resources Board (ARB) and its Executive Officer to exempt new aftermarket
catalytic converter from the prohibitions of Vehicle Code Section 27156.

WHEREAS, Car Sound Exhaust System, Inc. (Car Sound) of 22961 Arroyo Vista,
Rancho Santa Margarita, California 92688, has applied to the ARB for exemption
from the prohibitions in Vehicle Code Sections 27156 and 38391 to market their
aftermarket series 98000 three—way plus oxidation catalytic converter {TWC +
OC) for the following application, except for vethles equipped with an on—
board diagnostic II system:

WHEREAS, pursuant to the authority vested in the Executive Officer by Health
and Safety Code Section 39515 and in the Chief, Mobile Source Operations
Division by Health and Safety Code Section 39516 and Executive Order G—45—9,
the ARB finds that the above aftermarket catalytic converter complies with the
California Vehicle Code Section 27156 and Title 13, California Code of
Regulations, Section 2222(h).  Emission performance of the catalytic converter
was based on durability bench—aging of the catalyst using Johnson Matthey
bench—aging cycle EDC—53 for 25 hours, accepted by the ARB, for this
application, to be equivalent to 25,000 miles durability mileage accumulation
using AMA driving cycle (Reference Appendix IV, Title 40, part 86, Code of
Federal Regulations     (June 28,    1977)).

Whereas, emissions tests conducted at Automotive Testing and Development
Services (ATDS), Ontario, showed the following conversion efficiencies which
meet the minimum requirements for new aftermarket catalytic converters.  These
conversion efficiencies are within 10 percent or less of any Car Sound Exhaust
System, Inc.‘s exempted catalytic converter with the highest conversion
efficiencies within the same application limits as series 98000.

                         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 98000 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 Johnson Matthey.            The new aftermarket catalyst is

intended for the following vehicle application:

The new series 98000 TWC + OC has the same application as Car Sound‘s serie; 94000 TwC

+ OC,.    However, palladium was replaced with platinum and Johnson Matthey‘s washcoat

process JM2Z01/JM190     (front/rear)   was replaced by their new washcoat process

XS114/XS114    (front/rear).    The applicant claimed that the new washcoat process enabled

them to reduce noble metal loading on series 98000 catalyst and still meet the

required conversion efficiencies for the Vehicle Code Section 27156 exemption.                   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 that are

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

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 hew

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

Title 13, California.Code of Régulations, 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—20 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 platinum and

rhodium in 2:1 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 with ceria and zirconium 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 heat shiéld 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 direct 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,vand five years or

SD,ODO-miles on the container or shell, and the end pipes.

v.         DEVICE REVALUATION

           Car Sound submitted data from testing conducted by Automotive Testing and

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

Johnson Matthey using their EDC—53 bench—aging cycle for 25 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 (ZTW) 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 ETW 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 5.9L/6,000 ibs., 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 §,000 pounds.           The test

cat;lysts were labeled as 94JJ1 and 940J2.        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:
