The AP Exhaust 644021 is a direct-fit, 24-inch catalytic converter with a ceramic substrate and a 409 stainless steel shell. It is certified to CARB and Federal EPA standards and sold as 50-state legal, so it can be registered in California and other CARB states. It is aimed at OBDII vehicles needing an OE-style replacement, and the included gasket and factory-style mounting make it a bolt-on job for a competent DIYer. Against universal-fit converters it costs more engineering but saves fabrication; against OEM dealer parts it is the value route, though long-term durability reports are mixed.
