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:

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. Convertermake TestWt.(lbs.)
