Eastern Convertors 50549 Catalytic Converter with Integrated Exhaust Manifold - Front Left

Direct-Fit Catalytic Converter Manifold

Eastern Convertors 50549 is a direct-fit catalytic converter with integrated exhaust manifold for specific front left applications. Built to OE dimensions for the radiator side, it is made for a clean fit on select Chevrolet, Buick, and Cadillac vehicles with the correct emissions configuration.

The DIRECT FIT product line focuses on exact fitment and consistent installation geometry. For buyers replacing a front-left manifold converter, this line is aimed at reducing fitment guesswork while maintaining the factory-style layout required for the application.

Key Features

• Federal / EPA direct-fit manifold design
• Integrated exhaust manifold and catalytic converter assembly
• 4-bolt welded inlet type
• 2-bolt welded outlet type
• 2 O2 sensor ports
• 16-inch overall length
• ECO GM catalyst type
• Built to OE dimensions using advanced manufacturing processes
• NANO substrate chemistry for efficient catalyst loading

Fitment Details

• Fits 2014-2018 Chevrolet Impala, front left, radiator side. Legal note: Not for sale or use in the State of CA, CO, ME & NY (vehicles with CA emissions).
• Fits 2012-2016 Buick LaCrosse, front left, PZEV emissions, radiator side. Legal note: Not for sale or use in the State of CA, CO, ME & NY (vehicles with CA emissions).
• Fits 2013-2016 Cadillac XTS, front left, radiator side. Legal note: Not for sale or use in the State of CA, CO, ME & NY (vehicles with CA emissions).

What This Part Helps Address

• Failed catalytic converter efficiency codes
• Cracked or leaking exhaust manifold assembly
• Exhaust noise from manifold or flange leakage
• Check engine light related to catalyst performance or O2 sensor readings
• Factory-style replacement needs for front-left exhaust routing

Installation Notes

Confirm the vehicle’s emissions configuration, engine layout, and front-left radiator-side placement before installation. This part uses a 4-bolt welded inlet, a 2-bolt welded outlet, and two O2 sensor ports, so sensor and flange alignment should be checked against the original assembly. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Eastern Convertors uses automated workstations, spinner welding equipment, and high-speed production lines to build converters to OE dimensions and fitment standards. The NANO substrate chemistry is used to support efficient catalyst loading and consistent converter performance. Part number 50549 is part of the Eastern Convertors DIRECT FIT line for application-specific exhaust replacement.
