SUMMARY Car Sound Exhaust Systems, Inc. (Car Soufid) of 22961 Arroyo Vista, Rancho Santa Margarita, California 92688 has applied for an exemption of its series 53000 new aftermarket three—way catalytic converter (TWC) from the prohibitions in Vehicle Code Section 27156, in accordance with California regulations for new aftermarket catalytic converters. The catalytic converter is manutactured in a round configuration. The two test catalysts were aged using Johnson Matthey‘s rapid aging cycle, EDC—53, which has been accepted by the Air Resources Board for aging catal;/sts designed for vehicle application limits of 5.9L/6,000 lbs. The new TWC has a single substrate of ceramic monolith type and coated with platinum and rhodium in é 4:1 ratio. The emission tests were conducted on a 1994 Jeep Grand Cherokee 4.0L, equipped with a TWC, at the equivalent test weight of 4,250 pounds (Ibs.). The new catalytic converter is for installation on vehicles equipped with a single TWC. Thé maximum application limits for the new series 53000 TWC are 4.0L and 4,250 lbs., which corresponds to 4.0L engine displacement and gross vehicle weight rating of 4550 lbs. Emissions data submitted by the applicant show that the catalytic converter meets the requirements of Vehicle Code Section 27156 and Title 13, California Code of Regulations, Section 2222(h) for the stated applications. Based on the above, the staff recommends that the exemption be granted as requested and that Executive Order D—193—21 be issued.

EVALUATION OF CAR SOUND EXHAUST SYSTEMS, INC.‘S SERIES 53000 NEW AFTERMARKET THREE—WAY CATALYTIC CONVERTER FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156, AND TITLE 13, CALIFORNIA CODE OF REGULATIONS SECTION 2222(h) & INTRODUCTION Car Sound Exhaust Systems, Inc. (Car Sound) of 22961 Arroyo Vista, Rancho Santa Margarita, California 92688, has applied for an exemption from the prohibitions ir'1 Vehicle Code Section 27156 for its series 53000 new aftermarket three—way catalytic converter (TWC) in accordance with California regulations for new aftermarket catalytic converters. The new aftermarket catalytic converter ts.intended for the following vehicle application: Converter Type PN/Series Max, Eng. Size Max. Veh, Test Wt. TWC 53000 4.0L 4,250 lbs. — The maximum Gross Vehicle Weight Rating (GVWR) for the catalytic converter application is 4,550 Ibs. Car Sound intends to market the new converter as a replacement for catalytic converters on in—use vehicles whose manufacturer‘s warranty has expired and the need for replacement of the original equipment manufacturer (OEM) catalytic converter has been established and documented. The converter cannot be installed on vehicles equipped with an On—Board Diagnostic If (OBD—!1) system. {1. 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 catalytic converter mests the criterié set forth in Vehicle Code Section 27156, and Title 138, California Code of Regulations, Section 2222(h) for the stated application.

HL. RECOMMENDATION Staff recommends that the exemption be granted as requested and that Executive Order No. D—193—21 be issued, permitting the advertisement, sale, and installation of the new aftermarket catalytic converter on applicable vehicles. IV. DEVICE DESCRIPTION Car Sound‘s series 53000 new aftermarket catalytic converter is designed to use a single round~shéped ceramic monolith substrate. The substrate is $.66 inches in diameter and 2.93 inches in length. The substrate volume is 30.8 cubic inches. The substrate is coated with platinum and rhodium in a 4:1 rajtio, The substrate is contained in an outer 409 stainless steel shell with compressed intumescent or expanding mat to prevent vibration and exhaust by—pass. The shell haives are sealed by seam weld, and the end pipes are attached to the shell by arc welding. An éluminized heat shield is spot—wéjded to the upper side of the converter to protect the vehicle frdm excessive heat. The catalytic converter is _sold as a unit with installation instructions or used in customized direct fit exhaust applications. It is sold with a warranty for 25,000 miles on the substrate, and five years or 50,000 miles on the container or shell and the end pipes. V. DEVICE EVALUATION Car Sound submitted data frorfi testing conducted by California Environmental _ Engineering (CEE) laboratory located in Santa Ana, California. Catalyst bench—aging was conducted by the catalyst supplier, Johnson Matthey using its bench—aging cycle EDC—53. Emissions tests were conducted on a 1994 Jeep Grand Cherokee 4.0L equipped with a TWC, at the equivalent test weight of 4,250 lbs. The evaluation of Car Sound‘s new aftermarket catalytic converter is based on the bench—aging conducted by 'Johnson Matthey and the emission tests conducted at CEE. —2.

The limits of application of Car Sound‘s series 53000 TWC are 4.0L/4,250 lbs. with a corresponding maximum gross vehicle weight of 4,550 Ibs. The two test catalysts were labeled 1023D401/36382 and 1023C401/36389 respectively. Testing consisted ofA two cold—start CVS— 75 tests with a simulator ("dummy" catalyst), followed by two cold—start CVS—75 tests for each of the test catalysts. The average of the two test results for each test catalyst was used to calculate the conversion éefficiency. The overall conversion efficiency for the catalyst model is the average conversion efficiency of the two test catalysts. The test results for the catalyst are shown betow: California Environmental Engineering, Santa Ana. California TWC Simulator Catalyst 36382 Catalyst 36389 Conv. Eff. . Average Average Average Average HC (g/mi) 2.044 0.576 0.544 72.6% CO (g/mi) 15.451 3.609 2.998 78.6% NOx (g/mi) 4.587 1.381 1.283 71.0% The conversion efficiencies of the catalytic converter meet the minimum requirements of the California regulations for new aftermarket catalytic converters.‘ The ARB did not conduct confirmatory testing on the catalyst.
