Product Details

Walker EPA 50586 is part of the Ultra Direct-Fit Catalytic Converter line, which focuses on OE-style fitment and emissions compliance for import and domestic OBDII vehicles. This unit uses a stainless steel body, a round converter shape, and a direct-fit layout to match the factory exhaust configuration on the listed Ram applications. The overall length measures 61.790 inches, with a 2.962-inch inlet inside diameter and a 3.500-inch outlet outside diameter. This part cross-references Gates 21513 for the same application.

The part number 50586 is also useful when searching for a direct-fit catalytic converter for Ram 2500 and Ram 3500 EPA applications.

Common Problems This Part Can Address

• Check engine light related to catalytic converter efficiency
• Failed emissions inspection caused by a worn or damaged converter
• Restricted exhaust flow from internal substrate deterioration
• Exhaust leaks at the converter connection points
• Factory converter corrosion on high-mileage Ram 2500 and Ram 3500 trucks

Installation Notes and Tips

Verify the vehicle year, model, and left/right position before ordering. This converter uses a specific-fit design with a 2-bolt loose flange inlet and pipe connection outlet, so the existing exhaust configuration must match the listed application. Mounting hardware, inlet gasket, outlet gasket, clamps, and inlet hardware are not included. Confirm O2 sensor port alignment and inspect the surrounding exhaust components for wear before installation.
