The AP Exhaust Catalytic Converter (MPN 645890) catalyzes the conversion of regulated exhaust gases as they pass through, and it drops in as a Federal/EPA Direct-Fit replacement for the 2000-2005 Chevrolet Blazer, 2001-2004 Chevrolet S10, 2000-2003 GMC Jimmy, 2001-2004 GMC Sonoma, and 2000-2001 Oldsmobile Bravada — all with the V6-4.3L engine. If a clogged, cracked, or worn-out converter is behind a failed emissions test or a converter-related trouble code, this unit replaces it.

  • 409 stainless steel shell and neck: constructed for longer life.
  • Aristo Clean by Design catalyst technology: paired with a ceramic substrate to handle demanding emissions duty.
  • Direct-fit design: built to OE dimensions and fitment for the listed applications. Two 3-bolt loose-flange inlets with a spherical flare, a 2-bolt welded-flange outlet, and three sensor ports.
  • Gaskets included: two inlet gaskets and one outlet gasket. Mounting hardware is not included (Inlet Hardware: None, Outlet Hardware: None).

This is a Federal/EPA converter and is not CARB certified, so it is intended for use in states that do not require a CARB-compliant replacement converter. Overall length is 59.250 in. Country of origin: United States.
