MagnaFlow 5411770 California Grade CARB Compliant Direct-Fit Catalytic Converter

The MagnaFlow 5411770 is a California Grade CARB Compliant Direct-Fit Catalytic Converter engineered as a precise OE replacement. Built with a spun-body stainless steel construction and a ceramic substrate, this converter is developed using MagnaFlow's state-of-the-art 3D scanning metrology systems to ensure an exact fit and function matching the original equipment.

Installation is straightforward with bolt-on inlet and outlet connections — no cutting, welding, or fabrication required. The single laser fusion weld replicates the OE spun body design to minimize the risk of exhaust leaks, while the compact, low-mass design promotes greater thermal efficiency. Free-flowing mandrel-bent stainless steel tubing and OEM-like O2 sensor port locations further simplify the installation process.
