Detailed Description

Eastern Convertors 40642 is engineered for the front right, firewall-side exhaust location on select Toyota and Lexus applications. It combines the catalytic converter and exhaust manifold into one direct-fit assembly, which helps match the original exhaust layout on 2004-2007 Toyota Highlander, 2004-2006 Lexus RX330, and 2004-2006 Toyota Sienna models. The ECO II catalyst and NANO substrate chemistry are used to support efficient catalyst loading while maintaining a cost-conscious OE-style replacement format.

The DIRECT FIT product line is built using automated manufacturing, spinner welding, and high-speed production processes to maintain dimensional accuracy and consistent fitment. Part number 40642 is a practical choice when replacing a worn or damaged manifold converter on the specified Toyota Highlander, Lexus RX330, or Toyota Sienna front right position.

Common Repair Uses

• Replacing a cracked or leaking exhaust manifold converter
• Restoring exhaust sealing at the firewall-side front right location
• Addressing catalyst efficiency faults tied to the manifold converter assembly
• Correcting exhaust noise from a damaged manifold or flange area
• Replacing a rusted or heat-damaged OE-style exhaust unit

Installation Notes

Verify the vehicle’s emissions configuration before ordering. This Federal / EPA direct-fit manifold is not for sale or use in California, Colorado, Maine, or New York on vehicles with California emissions. Confirm the front right, firewall-side location, O2 sensor port count, and flange style before installation. Part number 40642 is intended for direct replacement on the listed applications, but final fit should always be matched to the vehicle’s original exhaust layout.

Quality Assurance

Eastern Convertors uses advanced manufacturing methods to build converters to OE dimensions and fitment standards. The DIRECT FIT line is produced with controlled welding and substrate technology to support consistent assembly quality and repeatable installation on the specified Toyota Highlander, Lexus RX330, and Toyota Sienna applications.
