Eastern Convertors 40777 Catalytic Converter with Integrated Exhaust Manifold - Front Right

Direct-Fit Catalytic Converter Manifold

Eastern Convertors DIRECT FIT Part Number 40777 is a catalytic converter with integrated exhaust manifold for specific Mitsubishi front-right applications. It is built to OE dimensions for direct replacement service on the firewall side, with Federal / EPA direct-fit manifold construction for the 2004-2009 Mitsubishi Galant and 2006-2012 Mitsubishi Eclipse.

Key Features

• Federal / EPA direct-fit manifold design
• ECO III catalyst type
• Integrated exhaust manifold construction
• 7-bolt welded inlet and 2-bolt welded outlet
• 2 O2 sensor ports
• 18-inch overall length
• Built using automated production and spinner welding processes for OE-style dimensions
• NANO substrate chemistry for efficient catalyst loading

Product Details

This Eastern Convertors catalytic converter manifold is engineered for direct replacement on the front right side of the vehicle, also identified as the firewall side. Part Number 40777 is listed for the 2006-2012 Mitsubishi Eclipse and the 2004-2009 Mitsubishi Galant, making it a focused fitment for drivers searching for a Mitsubishi Eclipse catalytic converter manifold or a Mitsubishi Galant front right exhaust manifold converter. The DIRECT FIT line emphasizes OE-matched dimensions and fitment consistency, while the ECO III catalyst and NANO substrate chemistry support efficient exhaust aftertreatment in a compact manifold assembly.

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

Common Repair Uses

• Replacement for a cracked or leaking exhaust manifold and converter assembly
• Restoration of exhaust flow after catalyst efficiency deterioration
• Repair for exhaust odor, rattling, or manifold flange leakage
• Service solution for O2 sensor-related exhaust system faults at the manifold location
• Direct replacement when the original front-right manifold converter no longer seals correctly

Installation Notes

Verify the vehicle’s emissions configuration before ordering. This part is not for sale or use in California, Colorado, Maine, or New York for vehicles with California emissions. Confirm the front-right, firewall-side location, the 7-bolt welded inlet, the 2-bolt welded outlet, and the presence of 2 O2 sensor ports before installation. The outlet hardware is listed as included; inlet hardware is not listed.

Quality Assurance

Eastern Convertors uses automated workstations, spinner welding equipment, and high-speed production lines to build converters to exact OE dimensions. The DIRECT FIT product line is focused on consistent fitment and efficient catalyst construction for replacement service.
