MagnaFlow 2001-2003 Toyota Sienna California Grade CARB Compliant Direct-Fit Catalytic Converter

This MagnaFlow direct-fit catalytic converter (Part Number 447207) is engineered for easy bolt-on installation by professional installers, eliminating the need for welding, cutting, or tube-bending. It features a ribbed body that minimizes expansion and distortion when the converter heats up. The ribs create a channel that protects the cushioning mat from direct exposure to exhaust gases and ensures proper alignment of the ceramic catalyst. These converters utilize a monolithic honeycomb catalyst with a ceramic coating designed for maximum flow and surface area. The coating process is meticulously controlled to maintain precise specifications, preventing flow restrictions or emissions test failures. Designed to exact OE specifications, this catalytic converter is legal for use in California and other CARB-restricted states, as it meets or exceeds California Air Resource Board requirements and holds CARB EO Number D-193-103.
