Keep your Dodge Durango's exhaust flowing and emissions under control with the Walker Ultra EPA Direct-Fit Catalytic Converter 56091. This stainless steel, standard oval converter installs as a direct-fit, bolt-on replacement for the 2000–2003 Dodge Durango, with a 2.5" inlet and a 2.5" outlet so it drops in without special fabrication or welding. The inlet uses a 2-bolt loose flange with spherical flare and the outlet is a pipe connection.

  • Direct-Fit Design: bolt-on replacement with factory-style routings, brackets, hangers and heat shields for an easy install that doesn't require specialized fabrication or welding.
  • Emissions Performance: OE-style high-technology washcoat and precious metal load deliver the required reduction in tailpipe emissions to match the vehicle application; if a failed converter is setting an emissions code, this replaces it.
  • Strong and Durable: thick OE-style flanges, hangers and brackets for strength and durability.
  • OE-Style Heat Protection: aluminized heat shields where originally equipped help protect the undercarriage from heat created by the converter.

Designed to comply with EPA standards for OBDII vehicles. It is not CARB certified and is not legal for sale or use in California, Colorado, or New York; in Maine it is legal only on EPA Federal Emission Equipped vehicles—consult your state's aftermarket converter regulations. Made in the United States and backed by Walker's 25,000-mile/40,000 km emissions warranty and a 5-year 50,000-mile/80,000 km structural integrity warranty.
