MagnaFlow Conv DF 01 Ford Lightning 5.4L

This Magnaflow California Grade CARB Compliant Direct-Fit Catalytic Converter, part number 447151, is designed specifically for your 2001 Ford F-150 Lightning with the 5.4L engine. It's built to keep your check engine light off and ensure your vehicle meets emissions standards, especially in California and other CARB-restricted states. You'll receive the converter itself, along with the necessary bolt and essential gaskets and hardware for installation, meaning you have what you need to get the job done without needing to source extra pieces.

Crafted with free-flowing mandrel-bent tubing and a highly corrosion-resistant stainless steel construction, this converter is built for a long service life. Magnaflow uses advanced 3D scanning during their research and development to ensure this part fits and functions just like the original equipment. The single laser fusion weld is designed to greatly reduce the possibility of leaks, and its compact, low-mass design contributes to greater thermal efficiency. The tubing is made from strong 16-gauge 409 stainless steel for exceptional corrosion resistance, and the OE-sized barbed exhaust hangers are made from 410 stainless steel to help reduce noise and vibration. This converter replicates the original equipment's flow dynamics, maintaining factory performance and fuel efficiency.

Installation is simplified because this is a direct-fit unit, meaning no cutting or welding is required when you have the proper tools. Magnaflow specializes in exhaust technology and designs each converter to exact original equipment specifications, giving you confidence in its performance and compliance.
