Product Details

Magnaflow is well-known for making exhaust components that flow well and last a long time. This direct-fit catalytic converter is built to keep your 2004 Ford Ranger or 2004 Mazda B3000 running cleanly and legally, especially if you're in California or another state with strict emissions rules. It's designed to replace your original converter without any cutting or welding, making installation much simpler with the right tools.

This converter uses mandrel-bent tubing, which means the inside diameter stays consistent throughout the bends, allowing exhaust gases to flow more freely than with crush-bent tubing. The construction is primarily 409 stainless steel for the tubing, which is strong and resists corrosion well, giving you a solid service life. Magnaflow uses 3D scanning to ensure this converter matches the original equipment's fit and geometry, so it should bolt right up. The welds are durable MIG welds, and the single laser fusion weld on the main body helps prevent leaks. It also includes a flange gasket to help you get a good seal during installation.

Because this converter is CARB compliant, it has undergone extra testing to meet California Air Resources Board requirements. This means it's legal for use in California and other states that follow CARB emissions standards. You'll also find that it interchanges with the original equipment part number 1F71-40-050.
