Detailed Description

AP Exhaust 641414 is a catalytic converter with integrated exhaust manifold for 2004-2007 Toyota Highlander models. The design combines the manifold and converter into one direct-fit assembly, helping maintain the original exhaust layout while matching OE dimensions. The stainless steel body and ceramic substrate support consistent exhaust treatment, and the welded flange configuration is built for a secure connection at the inlet and outlet. This part number, 641414, is intended for Federal / EPA applications and is listed for Toyota Highlander fitment in both N/A and front positions as shown in the catalog data.

AP Emissions Technologies uses ARISTO substrate chemistry and automated manufacturing processes to produce converters with efficient loading and controlled fitment. That manufacturing approach is reflected in the 641414 part number and in the OE-style dimensions required for Toyota Highlander exhaust service.

Common Repair Uses

• Replacing a damaged or restricted catalytic converter and manifold assembly.
• Restoring exhaust flow after substrate deterioration or internal blockage.
• Addressing emissions-related faults tied to converter efficiency.
• Repairing flange or gasket sealing issues in the exhaust manifold area.
• Servicing a direct-fit Toyota Highlander exhaust emissions component.

Installation Notes

Fits 2004-2007 Toyota Highlander, N/A. Fits 2004-2007 Toyota Highlander, front. Verify emissions compliance before installation, since the catalog notes Federal and California emissions coverage with state restrictions for CA, CO, ME, and NY. Confirm the vehicle’s emissions configuration and sensor layout before ordering. Part number 641414 should be matched to the exact application listed in the fitment data.

Quality Assurance

AP Exhaust states that its manufacturing process is built around OE dimensions and fitment control. The 641414 catalytic converter with integrated exhaust manifold is produced using automated workstations, spinner welding equipment, and high-speed production lines to support consistent build quality and application accuracy.
