Direct-Fit Converters

We offer over 2,500 Direct-fit converters for cars, vans, SUVs, and light trucks, all built to exact OE dimensions with OE-quality flanges and flex assemblies. Eastern Direct-fit converters cover over 100,000 applications including broad coverage for CARB applications.

Eastern Direct-fit converters feature our proprietary catalytic chemistry and high-flow design to maximize engine output and catalytic efficiency.

Most of our Direct-fit converters include our Value Pack installation kits with everything you need for a fast, easy installation, including hardware, gaskets, fasteners, studs, and accessories.

Where our engineers have recommended their use, post ‘96 Direct-fit converters use our new ECO II and ECO III catalysts.
