Recently, aftermarket catalysts have been introduced into commerce by several companies. These catalysts appear to be different than original equipment manufacturer (OEM) catalysts in one or more design features. These catalysts are also considerably less expensive than replacement OEM catalysts. The purpose of the report was to evaluate the efficiency of a group of aftermarket catalysts as a function of accumulated miles and to evaluate a single OEM catalyst at a single mileage point (83,161 miles) for comparison. Nine aftermarket catalysts were evaluated on one vehicle, which was provided by EPA. Catalyst evaluation was performed at Automotive Testing Laboratories, Inc. (ATL) in East Liberty, Ohio. Mileage was accumulated using other vehicles (five Impalas) by Hercules, Inc. of Cumberland, MD. The catalysts were evaluated for exhaust emissions conversion efficiencies and backpressure at each test point.
