MagnaFlow Conv DF 97-98 Ford Trucks 4.2L

When you're working on your 1997 or 1998 Ford F-150 with the 4.2L engine, and the check engine light is on due to emissions, this MagnaFlow California Grade Direct-Fit Catalytic Converter is what you need. This unit is designed to replace your original converter, helping to ensure your truck runs cleanly and legally, especially in California and other CARB-restricted states. It's built to meet or exceed California Air Resource Board requirements, so you can be confident it’s the right choice for emissions compliance.

What you get in the box is everything you need for a straightforward installation: the catalytic converter itself, one Torca clamp, two bolts, two flat washers, and two nuts. This means you won't have to scramble for hardware, especially if your factory bolts are rusted. The converter features free-flowing, mandrel-bent tubing that maintains smooth exhaust flow for optimal performance and fuel economy. It's constructed from highly corrosion-resistant stainless steel, specifically 16-gauge 409 stainless steel tubing for the main body and durable 308 stainless steel MIG welds, ensuring it holds up over time. MagnaFlow uses advanced 3D scanning during their research and development to ensure this converter fits precisely like the original equipment, and the single laser fusion weld is designed to minimize the chance of leaks.

This direct-fit design means no cutting or welding is required for installation, making it a job you can often tackle yourself with the right tools. The compact, low-mass design also contributes to better thermal efficiency. By replicating the OE design and flow dynamics, this converter helps maintain your truck's factory performance and fuel efficiency while keeping those emissions systems in check.
