The converter part numbers are shown below: converter Type Use Direct—Fit Part No. Universal—Fit Part No. TWC + OC oC 15555, 15558, 15561 15144, 15145, 15146, 15147 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—182—9 be issued, permitting the advertisement, sale and installation of the new aftermarket catalytic converter. IV. DEVICE DESCRIPTION Ceramic monolithic substrates which are coated with palladium and rhodium is used in the manufacture of the three—way plus oxidation catalyst. The substrates are enclosed in an outer stainless steel shell. Heat shields are welded on top and bottom of the converter shell. 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. DEVICE EVALUATION Walker has submitted the test data on the catalytic converter. The emission tests were conducted by Milton Roy Company (Milton Roy) in Orange, California. Two CVS—75 emission tests were conducted with the converter installed, followed by two CVS—75 tests with exhaust backpressure simulator. The two test catalytic converters were previously aged using a 1976 Pohtiac Station Wagon, and a 1975 Buick Electra, both powered by a 7,4L carbureted engine. The vehicle test weight used for the mileage accumulation was 5,500 lbs. The carry—over emission test vehicle was a 1975 Buick Riviera powered by a 7.4L carbureted engine using a test weight of 5,500 lbs. The test results and conversion efficiencies for the converter are shown below: Simulator Converter 1 Converter 2 Avg. Conv. Eff. HC (g/mi) 2.778 0.608 0.535 79 .4% co (g/mi) 10.782 1.554 1.635 85.2% All of the conversion efficiencies meet the requirements of the California regulations. The staff based the evaluation of the new aftermarket catalytic converter on the information submitted by Walker and on test data from Milton Roy.
