Magnaflow 08-10 Ford F-250 Super Duty 5.4L Direct Fit Converter

A failing catalytic converter on your Super Duty means a check engine light, failed emissions, and lost performance. MagnaFlow part number 5551760 is a California CARB-compliant direct-fit replacement built for the 2008-2010 Ford F-250 Super Duty and 2008-2010 Ford F-350 Super Duty with the 5.4L engine.

Direct-Fit, No Fabrication

MagnaFlow uses 3D scanning during development to replicate the factory exhaust routing precisely. That means this converter bolts into your existing exhaust system without cutting, welding, or custom fabrication. Mandrel-bent tubing keeps the internal diameter consistent throughout each bend, maintaining the smooth exhaust flow your 5.4L needs to run efficiently.

Tough Construction for Truck Duty

Super Duty trucks see hard use, and this converter is built accordingly. The body is 16-gauge 409 stainless steel, joined with 308 stainless steel MIG welds. The spun body design with a single laser fusion weld minimizes leak potential at the seam, while the compact, low-mass form factor allows for better heat management.

Legal in All 50 States

This converter meets California Air Resources Board standards and is legal for sale and installation in every state, including California, Colorado, New York, and Maine. Confirm your vehicle's Executive Order and Engine Family Number match the converter's CARB Executive Order before you install.
