Our take on the AP Exhaust 644016 Catalytic Converter

The AP Exhaust 644016 is a direct-fit, EPA-compliant catalytic converter with a ceramic substrate and a 409 stainless steel shell. It is built to OE dimensions so it bolts to the factory flange and hanger points without cutting or welding. It is a federal converter, so it fits vehicles sold outside California and is not legal for CARB states. Against OEM converters it is a lower-cost replacement with comparable fit; against universal weld-in units it saves installation labor. Owners of older trucks and cars use it to clear a P0420 code and pass a smog check.

Questions and answers

Is this converter legal in California?
No. It is EPA compliant only and has no CARB executive order, so it cannot be used in California or other CARB states.
Will it fit my vehicle?
It is a direct fit for specific year, make, engine and trim combinations. Check the AP Exhaust application chart for your exact vehicle before ordering.
Do I need to weld it?
No. It is designed to bolt to the factory flange and hangers on listed applications. Universal weld-in converters are the alternative for unlisted vehicles.
Will it clear my check-engine light?
It should clear a P0420 catalyst efficiency code if the converter is the cause. Fix any misfire or rich-running issue first, or the new unit can fail too.
What is it made of?
A 409 stainless steel shell around a ceramic substrate with a ceramic catalyst washcoat.
Does it come with gaskets and hardware?
Typically not. Reuse or replace the flange gaskets and fasteners for your application.
