The AP Exhaust 644076 is a direct-fit, EPA-compliant catalytic converter for the Buick Encore from 2013 to 2022. It uses a ceramic substrate and a two-bolt welded flange, and it bolts on in place of the factory unit with no fabrication. It is a federal EPA converter, not a California CARB-legal one, so check your state's rules before buying. Against OEM converters it is a lower-cost replacement with comparable fit; against universal weld-in converters it saves labor because it mounts directly.

Owner feedback on AP Exhaust direct-fit converters is limited but generally positive on fit and installation. Buyers mainly note that it bolts up like the original and quiets the exhaust again. Complaints center on durability in rust-belt cars and the California restriction.
