                                   SUMMARY



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

Rancho Santa Margarita, California 92688, has applied for an exemption to

use their new 900 series aftermarket three—way plus oxidation (TWC + OC)

catalytic converter in combination with the 500 series 3—way converter as

ma in converter and precatalyst system application under the California

regulations for new aftermarket catalytic converters.    Under this system

application, the 900 series is redesignated as 300.     Car Sound plans to use

the 300/500 system on 3—way plus oxidation vehicles up to 5.0 liters and

5500 lbs.    The 300/500 system is for vehicle application requiring two

precatalysts.

        Emissions data submitted show that the catalytic converter system

meets the requirements of Vehicle Code Section 27156 and Title 13,

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

Based on the above, the staff recommends that the exemption be granted as

requested.

EVALUATION OF CAR SOUND EXHAUST SYSTEM, INC. NEW AFTERMARKET 300/500 SERIES
    3—WAY PLUS OXIDATION MAIN CONVERTER AND PRECATALYST SYSTEM FOR EXEMPTION
     FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 AND TITLE 13,
               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

to use their new 900 series aftermarket three—way plus oxidation (TWC + 0C)

catalytic converter in combination with the 500 series 3—way converter as

main converter and precatalyst system application, in accordance with the

Califfornia regulations on new aftermarket catalytic converters.    The

intended application for the system is shown below:



TWC + OC                  304/504      5.0L (305 CID)         5500 lbs.

The 300/500 system is assembled with two 500 series converters as

precatalysts and one 300 as the main catalytic converter.

II.        CONCLUSION
           The applicant has submitted all the required information and based

on the submitted exhaust emissions test data, the staff concludes that the

catalytic converter system meets the criteria set forth in Vehicle Code

Section 27156 and Title 13, California Co&e of Regulations, Section 2222(h)

for the stated application.                                                ~

IIHI.      RECOM   ATION

           The staff recommends that the exemption be granted as requested and

that Executive Order No. D—193—6 be issued, permitting the advertisement,

sale and installation of the new aftermarket catalytic converter system.


IV.      EVIC       CRIPTION

        The Qubstrates of the Car Sound‘s three—way and three—way plus

cxidation substrates are coated with platinum, palladium and rhodium with

air injection incorporated between the reducing and oxidizing substrates of

the three—way plus oxidation converter.    Car Sound provided extended air

tube to permit air injection into the center of the main converter.       The

extra length of air tube was not required in the previously exempted Car

Sound 300/500 system for 5.2L vehicles.    The 300 and 500 series converters

are assembled with one reducing and one oxidizing substrates enclosed in an

outer stainless steel shell.    The 300 and 500 series converters have been

exempted previously by the Air Resources Board (ARB).     A heat shield of

aluminum is welded to the converter shell to protect the vehicle underbody

from heat.   The catalytic converter system is sold as a unit with

installation instructions and kits as shown in the application catalog.         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.

¥.      DEVICEEVALUATION
        Car Sound has submitted the test data on the 300/500 catalytic

converter system.    The tests were conducted by Automotive Testing and

Development Services, Inc. (ATDS), Huntington Beach, California.     Two CVS—75

emission tests were conducted on each of the test vehicles with the

converter installed and two CVS—75 tests were conducted with exhaust

backpressure simulator.   A 1989 Ford Thunderbird 5.0L was the test vehicle

for the 300/500 system.    The exemption for the 300/500 system application is

limited to vehicles up to 5.0L and 5500 lbs. in order to conform to the

"worst case" requirement of the California regulations.    The test results

and conversion efficiencies for the converter systems are shown below:

All of the conversion efficiencies meet the requirements of the California

regulations.     Car Sound conducted additionai tests to compare the

performance of their 300/500 system with original equipment manufacturer

(OEM) converter system.         A baseline test was first conducted with the

vehicle certification test weight of 3750 lbs., then with the higher Car

Sound test weight of 5000 ibs.         The OEM converter was then replaced by the

Car Sound system and the test conducted again with the Car Sound test weight

of 5500 lbs.     The test results below show that the Car Sound converter

system performed better than the existing OEM converter system.

The staff based the evaluation of the new aftermarket catalytic converter

systems on the information submitted by Car Sound and on test data from

Automotive Testing and Development Services, Inc.
