Product Overview

The MagnaFlow 60503 Direct-Fit Catalytic Converter is purpose-built for 2008–2010 Ford F-250 and F-350 Super Duty trucks equipped with the 6.4L Power Stroke Diesel (VIN R). This Diesel Oxidation Catalyst (DOC) restores factory emissions compliance and maintains proper exhaust flow without the need for tuning or modifications.

With a 37.75” overall length and round 12.75” spun-body converter, this unit installs easily using factory mounting points and includes a gasket for a leak-free seal. No clamps or additional hardware are needed for most installs, and bolt-on flange connections ensure easy servicing in the future.

Designed using 3D scanning and CNC precision welding, MagnaFlow ensures OE-quality fit and long-term durability. This converter is ideal for replacing failed or clogged DOCs while keeping emissions system integrity intact—without sacrificing performance or flow.
