Keep the exhaust on your full-size V8 van flowing and properly treated with the AP Exhaust Federal / EPA Direct-Fit Catalytic Converter 645863. A catalytic converter routes engine-out hydrocarbons, carbon monoxide, and oxides of nitrogen through a coated substrate to convert them into less-harmful gases, and this one installs in the right-side position on the 2003-2005 Chevrolet Express 2500 and 3500 and the 2003-2005 GMC Savana 2500 and 3500 with the V8-4.8L or V8-6.0L.
AP builds this converter to OE dimensions and fitment, and it connects through 3-bolt welded flanges at both the inlet and outlet.
- 409 stainless steel shell and neck construction for longer life.
- Ceramic substrate with Aristo Clean by Design catalyst technology and highly efficient loadings.
- 3-bolt welded flange inlet and outlet with inlet and outlet gaskets included; mounting hardware is not included.
- One sensor port and an overall length of 60.75 in.
This is a Federal / EPA converter and is not CARB-certified, so it is not legal for sale or use in California, New York, Maine, or other states requiring CARB-compliant replacement converters. If the original converter on your van has failed, this direct-fit unit replaces it and restores proper exhaust treatment. Made in the United States; one used per application. See the Buyer's Guide tab for the full application list.
