Direct-Fit Catalytic Converter for Toyota

AP Exhaust 642040 is a Federal / EPA direct-fit catalytic converter built for OE-style fitment and emissions performance. It is engineered for the right-side application on select Toyota Tundra and Toyota Sequoia models, with stainless steel body construction and a ceramic substrate for efficient exhaust flow and emissions control.

Key Features

  • Federal / EPA direct-fit catalytic converter
  • Stainless steel body for corrosion resistance
  • Ceramic substrate material
  • Built to exact OE dimensions and fitment
  • 3-bolt welded flange inlet and 2-bolt welded flange outlet
  • Includes inlet gasket and outlet gasket
  • Two O2 sensor ports
  • Overall length: 42 inches

Detailed Product Overview

AP Exhaust 642040 uses ARISTO substrate chemistry and advanced manufacturing methods to support efficient converter loading while maintaining precise OE-style dimensions. That combination helps deliver consistent fitment on the right side of 2007-2011 Toyota Tundra and 2008-2009 Toyota Sequoia applications. If you need a direct-fit catalytic converter for Toyota Tundra right side or a replacement catalytic converter for Toyota Sequoia right side, this part is built for those vehicle-specific requirements. This part cross-references 17410-0F090 for the same application.

What This Part Helps Address

  • Failed or restricted catalytic converter causing emissions-related trouble codes
  • Reduced exhaust flow from a deteriorated substrate
  • Exhaust leaks at the converter flange connections
  • Check engine light concerns tied to catalyst efficiency
  • Replacement needs after corrosion or internal converter damage

Installation Notes and Tips

Verify the vehicle is a right-side application before ordering. This converter uses a 3-bolt welded flange inlet and a 2-bolt welded flange outlet, with inlet and outlet gaskets included and no inlet or outlet hardware listed. Confirm O2 sensor port locations and compare the original converter to AP Exhaust 642040 before installation. Fitment includes 2007-2011 Toyota Tundra, right, and 2008-2009 Toyota Sequoia, right.

Quality Assurance

AP Exhaust builds this converter to OE dimensions using automated workstations, spinner welding equipment, and high-speed production lines to support consistent fitment and manufacturing accuracy. The Federal / EPA direct-fit design is intended for the listed applications only, and emissions compliance restrictions apply in CA, CO, ME, and NY as noted for the fitment.
