MagnaFlow Conv DF Mustang 04 4.6L CA

This is the MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter, part number 454018, specifically for your 2004 Ford Mustang with the 4.6L engine. If you're in California or another state with strict emissions requirements, this converter is designed to keep your check engine light off and ensure your vehicle passes inspection. It's built to meet or exceed California Air Resource Board (CARB) guidelines, meaning it's legal for use in California and other CARB-restricted areas.

MagnaFlow uses advanced 3D scanning during their research and development to ensure this converter fits and functions just like the original equipment. The tubing is mandrel-bent for smooth exhaust flow, which helps maintain peak fuel economy. It's constructed from highly corrosion-resistant 409 stainless steel for a long service life, and the single laser fusion weld is designed to greatly reduce the possibility of leaks. This converter also features a compact, low-mass design for better thermal efficiency.

Installation is made simpler because this is a direct-fit unit, meaning no cutting or welding is required. MagnaFlow includes everything you need to get the job done: four O2 port plugs, a flange gasket, two Torca clamps, and four nuts. The Torca AccuSeal clamps provide a full 360-degree, equally distributed clamping force to prevent pipe distortion.
