MagnaFlow Conv DF 04 Ranger/BSer rr 3.0L

If your 2004-2006 Ford Ranger or Mazda B3000/B4000 is showing a check engine light related to emissions, it's likely time to replace the catalytic converter. This direct-fit unit from Magnaflow is built to meet California Air Resource Board (CARB) requirements, meaning it's legal for use in California and other states with strict emissions standards. It's designed to keep that check engine light off and ensure your truck is running cleanly.

What sets this converter apart is its construction and design. It features free-flowing, mandrel-bent tubing made from 16-gauge 409 stainless steel, which is highly resistant to corrosion and built to last. Magnaflow uses advanced 3D scanning to ensure this converter matches the original equipment's fit and geometry, so you get smooth exhaust flow and maintain factory performance. The compact, low-mass design also helps with thermal efficiency, and the single laser fusion weld greatly reduces the chance of exhaust leaks. Plus, it comes with the necessary gaskets to help you get a proper seal during installation.

Because this is a direct-fit converter, installation is straightforward. There's no cutting or welding required, making it a job you can tackle with the right tools. This converter interchanges with several OE part numbers, including 1F71-20-500 and 1F71-20-500A, so you can be confident it's the right replacement for your vehicle.
