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

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

catalytic converter under the California requlations for new aftermarket

catalytic converters.   Car Sound plans to use the converter on three—way

plus oxidation vehicles up to 5.8 liters and 5500 lbs.

        Emissions data submitted show that the catalytic converter meets the

requirements of Vehicle Code Section 27156 and Title 13, California Code of

Requlations, Section 2222(h) for the stated application.   Based on the

above, the staff recommends that the exemption be granted as requested.

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

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

for their new aftermarket 900 HD series three—way plus oxidation {TWC + OC)

catalytic converter, in accordance with the California requlations on new

aftermarket catalytic converters.     The intended converter application is

shown below:



3—Way + OC               900 HD            5.8L {351 CID)    5500 Ibs



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 meets the criteria set forth in Vehicle Code Section

27156 and Title 13, California Code of Requlations, Section 2222(h) for the

stated application.

III.      RECOMMENDATION
          The staff recommends that the exemption be granted as requested and

that Executive Order No. D—193—4 be issued, permitting the advertisement,

sale and installation of the new aftermarket catalytic converter.


IY.     D          SCRIP

        The Car Sound three—way plus oxidation substrates are coated with

platinum, palladium and rhodium with air injection incorporated between the

reducing and oxidizing substrates.     Two reducing and one oxidizing

substrates are enclosed in an outer shell or container of stainless steel.

The converter shell is constructed of stainless steel 409.    A heat shield of

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

from heat.     The catalytic converter is sold 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.

v.                 VALUAT

        Car Sound has submitted the test data on the catalytic converter.

The tests were conducted by Automotive Testing and Development Services,

Inc. (ATDS), Huntington Beach, California.     Two CVS~75 emission tests were

conducted on the test vehicle with the converter installed and two C¥S—75

tests were conducted with exhaust backpressure simulator.     The substrates

that were used to build theYSOO HD converter were respectively aged on 7.5

and 5.0 liter vehicles with 5500 lbs. weight.    Exemption for the 900 HD

series converter is limited to vehicles up to 5.8 liters and 5500 Ibs. in

order to conform to the "worst case" requirement of the California

regulations.    The test results and conversion efficiencies for the converter

are shown below:


                        ge—        1      xidation       +_ 0C



           Simulator          Converter        Conversion Efficiency

HC (g/mi) 5.007                0.643                 a7.2%
CO (g/mi) 61.092               9.528                 8g4 .4%
NOx(g/mi) 1.654                o.816                 50.7%

All of the conversion efficiencies meet the requirements of the California

regulations.   Car Sound did measurements to compafe the vehicle exhaust

backpressure for the original equipment manufacturer converter and the

series 900 HD converter.      The result showed no significant change in

backpressure due to the installation of the new converter.       The staff based

the evaluation of the new aftermarket catalytic convertar on the information

submitted by Car Sound and on test data from Automotive Testing and

Development Services, Inc.
