Eastern Manufacturing was founded by Wilhelm Schafer in 1976 as a company to re-manufacture catalytic converters. Eastern supplied its re-manufactured cat converters to Schafer's other companies: Schafer Muffler Centers and S.M.S. Products. Within a few years of its establishment, the company started producing brand-new catalytic converters in universal and direct-fit variations. Eastern has its headquarters in Langhorne, Pennsylvania from where it supplies its parts to over 72 countries across the world.


Currently, the brand offers a range of aftermarket catalytic converters and is a supplier of OEM parts for makes including Fiat and Kia. The company's catalytic converters are offered for a range of diesel and high performance applications. All Eastern catalytic converters are manufactured in the USA and come with a 5-year or 50,000-mile Eastern Catalytic Warranty.


Catalytic converters, a part of the exhaust system in automobiles, serve the purpose of reducing the quantity of toxic pollutants in the exhaust gases and expel them as less hazardous gases. The catalytic converter burns the un-burnt fuel in the exhaust and reduces the amount of hydrocarbons and carbon monoxide in it. The catalytic converters should meet the compliance standards of the country/state in which they are used. Eastern manufactures a range of cat converters that meet the compliance standards of different regions. In the United States, the brand's catalytic converters meet the requirements to be used in cars featuring OBDII engines. Eastern also produces CARB catalytic converters. In the European continent, Eastern's catalytic converters have got Euro II and Euro III certifications. Across the world, the brand's cat converters have earned over 100 certifications.


Eastern's signature series of cat converters is the ECO Series which can be fit into applications with low or high emissions. The line of ECO Series catalytic converters includes ECO CARB, ECO II, ECO III and ECO GM variations. The brand's direct-fit catalytic converters come with Value Pack installation kits that include the necessary parts which help in installing the cat converters. The kit contains gaskets, fasteners, studs and other accessories.

The company also offers cat converters designed with up to 6″ diameters for custom applications.
