Keep exhaust flowing and emissions in check with the AP Exhaust Catalytic Converter 644014, a Federal/EPA direct-fit converter that houses a ceramic substrate to catalyze exhaust gases as they pass through. It installs as a direct-fit replacement for the 2006-2008 Buick Lucerne (V6-3.8L), matching the factory converter's connections for a straightforward swap.

  • 409 stainless steel shell and neck construction for longer life.
  • Ceramic substrate featuring Aristo Clean by Design® advanced catalyst technology to handle demanding emissions requirements.
  • Two-bolt welded flange at both the inlet and outlet, with one sensor port for the oxygen sensor.
  • Inlet and outlet gaskets included; no mounting hardware is supplied — consult the vehicle service information for the correct hardware.

Overall length is 22.810 inches. This is a Federal/EPA converter and is not CARB-certified, so it is not legal for sale or use on vehicles required to run a CARB-compliant converter, such as those registered in California and New York. If a clogged, damaged, or failed original converter is the cause of your emissions or performance issue, this replaces it. Country of origin: United States.
