Keep your Toyota Sequoia's exhaust flowing cleanly and its emissions system in spec with the Walker CalCat Direct-Fit Catalytic Converter, MPN 83454. It installs as a direct-fit, bolt-on replacement for the 2001-2004 Toyota Sequoia — see the Buyer's Guide tab for engine-level fitment.

  • CARB compliant: Designed, tested and validated to meet CARB performance requirements; legal for sale in California, Colorado, New York and other states requiring CARB-compliant replacement converters. Consult your state's aftermarket converter regulations.
  • Direct-fit design: A bolt-on replacement fitted with factory-style routings, brackets and hangers, so installation needs no specialized fabrication or welding.
  • Durable construction: Stainless-steel body with aluminized pipe and heat shields, plus thick flanges and brackets for strength.
  • Consistent catalyst performance: A precise OE-style coating process coats the substrate with catalyst material for consistent emissions performance, using a high-technology washcoat.
  • Outlet size: 1.92" outlet (OD).

Backed by Walker's 50,000-mile / 80,000-kilometer coverage against burn-out and structural failure. If a failed or restricted converter is the cause of a check-engine light or a failed emissions test on your Sequoia, this replaces it.
