MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 5491231

This direct-fit catalytic converter is designed to replace the factory unit on 2010-2012 Toyota 4Runner (and compatible with 2010-2011 Toyota FJ Cruiser), providing CARB-compliant emissions control for use in California and other CARB-regulated states. Built by MagnaFlow to match OE dimensions and flow characteristics, this converter uses a spun-body design with a single laser fusion weld and mandrel-bent tubing to maintain proper exhaust geometry. Constructed from corrosion-resistant stainless steel, it includes gaskets and hardware for a proper seal and installation without cutting or welding when using the correct tools. The compact, low-mass design supports efficient thermal behavior while helping avoid exhaust leaks when installed per vehicle requirements. This unit is intended for customers who want a reliable, CARB-approved replacement that fits and functions like the original equipment. Legal for sale in all 50 states including California, Colorado, New York and Maine. Installation is permitted only if the vehicle’s Executive Order number and Engine Family Number appear in this converter’s CARB Executive Order.
