AP Exhaust 641349 Catalytic Converter with Integrated Exhaust Manifold - Front Right or Right

Direct-Fit Catalytic Converter Manifold

AP Exhaust 641349 is a Federal / EPA direct-fit catalytic converter with integrated exhaust manifold for select Toyota applications. It is built with a stainless steel body, ceramic substrate, and OE-style dimensions to support proper fitment on the vehicle side of the exhaust system.

Fits 2003-2009 Toyota 4Runner, right. Fits 2007-2009 Toyota FJ Cruiser, right. Fits 2005-2008 Toyota Tacoma, front right. Fits 2005-2006 Toyota Tundra, front right. AP Exhaust 641349 is also listed for manifold-unit applications on the same Toyota platforms.

Key Features

• Federal / EPA direct-fit catalytic converter with integrated exhaust manifold
• Stainless steel body for corrosion resistance in exhaust service
• Ceramic substrate material for emissions conversion performance
• OE-dimensioned construction for fitment accuracy
• 6-bolt welded flange inlet and 3-bolt welded flange outlet
• Includes inlet gasket, outlet gasket, and outlet hardware
• One O2 sensor port
• Overall length: 25 inches

Detailed Description

AP Exhaust 641349 is engineered for Toyota 4Runner, FJ Cruiser, Tacoma, and Tundra exhaust repairs where a direct-fit catalytic converter and manifold assembly is required. The stainless steel housing and ceramic substrate are paired with manufacturing processes that support consistent OE-style dimensions, helping the part align with factory mounting points and exhaust routing. This part cross-references OE numbers 17140-0P100 and 17150-31320 for the same application.

Use AP Exhaust 641349 when replacing a worn or restricted converter-manifold assembly on the right side of the exhaust system. The integrated design helps simplify replacement on vehicles that use a combined manifold and catalytic converter layout, including Toyota 4Runner and Toyota Tacoma applications.

What It Helps Address

• Check engine light concerns related to catalyst efficiency or exhaust flow
• Exhaust leaks at the manifold-to-pipe connection
• Restricted exhaust flow from a deteriorated converter substrate
• Fitment issues caused by damaged or corroded OE manifold assemblies
• Emissions test failures tied to a failed catalytic converter

Installation Notes

• Verify the vehicle’s emissions configuration before ordering.
• Fits 2003-2009 Toyota 4Runner, right; 2007-2009 Toyota FJ Cruiser, right; 2005-2008 Toyota Tacoma, front right; and 2005-2006 Toyota Tundra, front right.
• Federal and California emissions applications are listed, but this part is not for sale or use on vehicles licensed in CA, CO, ME, or NY.
• Confirm O2 sensor port location, flange style, and mounting orientation against the original assembly before installation.
• Professional installation is recommended for exhaust manifold and catalytic converter replacement.

Quality Assurance

AP Exhaust states that its manufacturing process uses automated workstations, spinner welding equipment, and high-speed production lines to maintain OE dimensions and fitment consistency. The ARISTO substrate chemistry is used to support efficient converter loading and competitive production quality across the AP Emissions Technologies line.
