AP Exhaust Catalytic Converter,Catalytic Converter-Direct Fit P/N:642766
Keep your exhaust flowing cleanly with the AP Exhaust Catalytic Converter (MPN 602206), a Federal/EPA converter that reduces harmful exhaust emissions as gases pass through its catalyst-coated substrate. It installs in the rear converter position as a replacement for a long list of pre-OBD-II applications, including the 1993 Asuna GT [L4-1.6L], 1975-1980 Buick Century [V6-3.8L], 1975-1980 Buick LeSabre [V8-5.7L], 1975-1982 Buick Regal, and hundreds more — see the Buyer's Guide tab for the full list of makes, models, years, and engine codes.
It uses 2.50 ID pipe necks on both the inlet and outlet, a ceramic substrate, and no sensor ports or air tube. This is a Federal/EPA converter that is NOT CARB certified, so it is not legal for sale or use in California or other states requiring CARB-compliant converters — confirm your state's emissions requirements before ordering. Made in the United States. Always diagnose the cause of an emissions fault before replacing the converter.
What does this catalytic converter do?
It routes exhaust gases through a catalyst-coated substrate to reduce harmful emissions. If a failed or restricted converter is the cause of your issue, this replaces it in the rear position.
Is this converter legal in California?
No. It is a Federal/EPA converter and is not CARB certified, so it is not legal for sale or use in California or other states requiring CARB-compliant converters.
What are the inlet and outlet connections?
Both the inlet and outlet use a 2.50 ID pipe neck. Confirm your vehicle's pipe sizing and routing before installing.
Will this fit my vehicle?

What is the converter shell made of?
It uses 409 stainless steel shell and neck construction for longer life, with a ceramic substrate and increased precious metals loading. Made in the United States.
