AP Exhaust 772794 Catalytic Converter - Center

CARB-Compliant Direct-Fit Catalytic Converter

AP Exhaust 772794 is a CARB compliant direct-fit catalytic converter built for California emissions applications on select Buick LaCrosse models. It uses a stainless steel body, a ceramic substrate, and OE-style 2-bolt welded flange connections for a direct replacement that matches factory dimensions and fitment.

Fits 2010-2016 Buick LaCrosse, center, with California emissions applications. This AP Exhaust AGMXJ03.0157 converter is engineered for the listed center-position fitments and includes one O2 sensor port.

Key Features

• CARB compliant direct-fit catalytic converter
• Stainless steel body for corrosion resistance
• Ceramic substrate material
• One O2 sensor port
• 2-bolt welded flange inlet and outlet connections
• Overall length: 54.63 in.
• Executive Order D-798-9

Product Details

The AP Exhaust AGMXJ03.0157 line is built around exact OE dimensions and fitment, using automated manufacturing and spinner welding processes to maintain consistent converter construction. AP Exhaust 772794 is part of that product line and is intended for California emissions-compliant replacement on the specified Buick LaCrosse center exhaust position. The design combines a stainless steel shell with a ceramic substrate to support proper exhaust flow and emissions control in the original application.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Failed or inefficient catalytic converter operation
• Check engine light concerns related to catalyst efficiency
• Emissions test failures on California-compliant vehicles
• Exhaust restriction caused by a worn converter
• Fitment issues from non-direct replacement parts

Installation Notes

Verify the vehicle’s year, model, center position, and California emissions configuration before installation. This converter uses 2-bolt welded flange inlet and outlet connections and includes one O2 sensor port. Outlet gasket is listed as included; inlet and outlet hardware are not included.

Quality Assurance

Built to OE dimensions and supported by Executive Order D-798-9 for the listed California applications, this converter is manufactured under AP Exhaust Holdings, LLC quality controls for consistent fitment and emissions compliance.
