Eastern Convertors 40656 Catalytic Converter with Integrated Exhaust Manifold - Front Left

Direct-Fit Catalytic Converter Manifold

Eastern Convertors DIRECT FIT Part Number 40656 is a Federal / EPA direct-fit catalytic converter with integrated exhaust manifold for select Honda, Acura, and Saturn applications. It is built to OE dimensions for accurate fitment and uses ECO II catalyst technology with a NANO substrate chemistry for efficient exhaust treatment.

This part is engineered for front left, radiator-side applications where the converter and manifold are combined into one assembly. It is a direct-fit replacement for vehicles such as the Honda Odyssey, Acura MDX, and Honda Pilot, with fitment coverage across multiple 2003-2010 applications.

Detailed Description

Eastern Convertors 40656 is part of the DIRECT FIT product line, which focuses on OE-style replacement exhaust components with application-specific dimensions and mounting points. The integrated manifold design simplifies replacement on vehicles that use a combined exhaust manifold and catalytic converter assembly, while the welded inlet and outlet configurations support a factory-style installation layout. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible With 2005-2010 Honda Odyssey, front left; 2003-2009 Acura MDX, front left; 2005-2008 Acura RL, front left; 2004-2008 Acura TL, front left; 2005-2008 Honda Pilot, front left; 2006-2008 Honda Ridgeline, front left; 2003-2007 Honda Accord, front left; and 2004-2007 Saturn Vue, front left. Use this part number 40656 when you need a direct-fit catalytic converter manifold for these specific front-left radiator-side applications.

Common Repair Uses

• Replacing a failed or restricted catalytic converter
• Restoring exhaust flow after manifold or converter damage
• Addressing emissions-related fault codes tied to catalyst efficiency
• Repairing exhaust leaks at the manifold-to-pipe connection
• Replacing a cracked or corroded integrated manifold assembly

Installation Notes

Verify engine configuration, emissions calibration, and front-left placement before ordering. This assembly uses a 4-bolt welded inlet, a 3-bolt welded outlet, and two O2 sensor ports, so sensor and flange alignment should be checked against the original unit. Professional installation is recommended to confirm proper sealing and sensor placement on the Honda Odyssey, Acura MDX, Honda Pilot, and other listed applications.

Quality Assurance

Eastern Convertors uses automated workstations, spinner welding equipment, and high-speed production lines to build converters to exact OE dimensions. The ECO II catalyst and proprietary NANO substrate chemistry are used to support efficient catalyst loading and consistent manufacturing output.
