Toyota Sienna Catalytic Converter - Underbody - Magnaflow - Direct Fit (2007–2010). A direct-fit replacement catalytic converter engineered to restore proper emissions control and help prevent a check engine light related to the underbody converter.
This MagnaFlow OEM-grade converter is built to match the factory fit and flow characteristics for 2007–2010 Toyota Sienna models and interchanges with OE part 17420-0P090. The spun-body design with a single laser fusion weld reduces potential leak points, while mandrel-bent tubing and corrosion-resistant stainless steel construction maintain OEM-like exhaust geometry for reliable operation. Installation is straightforward with included gaskets and hardware — no cutting or welding required when using proper tools. Designed to meet Federal EPA emissions requirements for OBD-II federally registered vehicles. Not legal for sale or installation in California, Colorado, or New York.
