Magnaflow Conv DF 03-04 4Runner 4.0L P/S

If your 2003 or 2004 Toyota 4Runner's check engine light is on due to emissions issues, replacing the catalytic converter is often the solution. This direct-fit converter from Magnaflow is built to keep your vehicle running cleanly and legally, meeting Federal EPA emissions requirements. It's designed to function just like the original equipment, ensuring your 4.0L engine performs as expected and maintains factory fuel efficiency.

Magnaflow builds this converter with a focus on durability and ease of installation. The tubing is made from strong 16-gauge 409 stainless steel, which resists corrosion and should last a long time. The spun body design replicates the original equipment, and a single laser fusion weld helps prevent leaks. Because it's a direct-fit part, you won't need to cut or weld anything to install it – just bolt it on using the included gaskets for a proper seal. Magnaflow uses advanced 3D scanning during development to ensure it fits right and works correctly.

This converter is designed for federal emissions systems. If your 4Runner is registered in California or a state that follows California emissions standards, this part is not legal for sale or use. Always refer to your vehicle's specific emissions system requirements and local regulations.
