Magnaflow 05-08 Ford E-350 Super Duty 5.4L Direct Fit Converter

MagnaFlow CARB Direct-Fit Catalytic Converter for 2007-2008 Ford E-Series Vans

If your Ford E-Series van is throwing a check engine light for a failing catalytic converter, this MagnaFlow unit (part 5582439) is built to drop right in without any cutting or welding. It fits the 2007-2008 Ford E-150, E-250, and E-350 Super Duty with the 5.4L engine, and it meets California Air Resources Board (CARB) requirements, so it is legal for sale and use in all 50 states including California and other CARB-restricted states.

Stainless steel construction runs throughout this converter. The tubing is 16-gauge 409 stainless steel with mandrel bends that follow the factory routing and geometry. Mandrel bending keeps the inside of each bend smooth and round rather than crimped, which helps maintain consistent exhaust flow and fuel economy. The welds are 308 stainless steel MIG welds, and the spun body design uses a single laser fusion weld to minimize the chance of exhaust leaks.

MagnaFlow uses 3D scanning during development to match the original equipment dimensions closely. That means the mounting points, hangers, and connection angles should line up with your factory exhaust without modification. A Torca AccuSeal clamp is included in the box, which applies even clamping force around the full 360 degrees of the pipe to prevent distortion.

Installation is straightforward for a bolt-on job. The kit comes with the gaskets and hardware you need, so you will not have to reuse corroded factory fasteners. For anyone working on a fleet van or a personal E-Series, this converter gets you back on the road and through emissions testing without a trip to the welding shop.
