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.
