Convert regulated exhaust pollutants with the Walker Exhaust CalCat CARB Universal Catalytic Converter 82637 — a universal-fit converter cataloged for a wide range of 1995–2005 GM cars and trucks, including the Buick LeSabre and Park Avenue, Cadillac DeVille and Seville, and Chevrolet Camaro. Its catalyst-coated substrate converts pollutants in the exhaust stream; if a failed converter is the cause of your emissions failure, this replaces it.
Universal design: a customizable body with expandable bushings for easier fitment; installation may require specialized fabrication and/or welding.
Durable build: stainless-steel body paired with an aluminized pipe and heat shields.
Consistent output: a factory-style coating process deposits the catalyst material onto the substrate for uniform performance, with a high-technology washcoat formulated to deliver superior performance compared with EPA-compliant converters.
Specs: 3" inlet inside diameter and 3" outlet inside diameter, both pipe connections; oval Premium-grade body. CARB-certified and legal for sale in California, Colorado, New York and other states requiring CARB-compliant replacement converters when used on an approved application. Backed by Walker's 50,000-mile/80,000-kilometer coverage for emissions and structural integrity. Mounting hardware is not included — consult the vehicle service information for the correct fasteners and installation. Country of origin: United States.
