MagnaFlow California CARB-Compliant Front Manifold Catalytic Converter - Toyota Sienna / Highlander / Lexus RX330 3.3L 2004-2007

The MagnaFlow 5582833 is a California Grade, CARB-compliant front manifold catalytic converter for the Bank 2 side of the 3.3L V6. It uses 16-gauge 409 stainless steel mandrel-bent tubing with a spun body that replicates the factory geometry, and a single laser fusion weld reduces leak points while the compact, low-mass design improves thermal efficiency. The gaskets and hardware needed for installation are included, avoiding the reuse of corroded factory parts, and 308 stainless MIG welds add durability for a bolt-in fit with no cutting or welding. It is CARB compliant and legal for sale and use in California and CARB states on the listed vehicles.
