The intended converter application is shown below: Type Part No. Max. Engine Size Max. Veh. Wt. TWC 28802,28833, 5.71 (350 CID) 6000 1bs. 28834 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 Regulations, 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—184—6 be issued, permitting the advertisement, sale and installation of the new aftermarket catalytic converter.

IV. DEVICE DESCRIPTION The Maremont three—way substrates are coated with palladium and rhodium. Air injection is not incorporated between the reducing and oxidizing substrates. The 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 Maremont‘s 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. DEVICE EVALUATION Maremont has submitted test data on the catalytic converter. The tests were conducted by Automotive Testing and Development Services, Inc. (ATDS), Huntington Beach, California. The two test catalysts were respectively aged on a 1988 Chevrolet Suburban, 5.7L with TBI (Throttle Body Injection), and a 1988 Chevrolet Silverado Pick—up, 5.7L with TBI. The conversion efficiency testing was conducted on a 1988 Chevrolet Cheyenne, 5.7L with TBI as a test vehicle. Two CVS—75 emission tests were conducted on the test vehicle with the converter installed and two CVS—75 tests were conducted with exhaust backpressure simulator. The vehicle test weight for all three vehicles was 6000 Tbs. The exemption for the converter is limited to vehicles up to 5.7 liters and 6000 lbs. 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:
