MagnaFlow Conv DF 99-02 4Runner 3.4L rear OEM

If you're working on a 1999-2002 Toyota 4Runner with the 3.4L engine and need to replace the catalytic converter, this direct-fit unit from Magnaflow is a solid option. It's designed to keep your check engine light off and ensure your vehicle meets federal emissions standards set by the EPA. This means it's legal for use on OBDII Federally registered vehicles, including those with California or Federal/EPA emission systems, though it's not CARB approved and cannot be shipped to California.

Magnaflow builds this converter with free-flowing, mandrel-bent tubing, which helps maintain factory performance and fuel efficiency by avoiding restrictions. The construction uses highly corrosion-resistant stainless steel, specifically 16-gauge 409 stainless steel for the tubing and 308 stainless steel for the MIG welds, to ensure a long service life. They use advanced 3D scanning during their design process to make sure this converter fits and functions just like the original equipment, and the single laser fusion weld is designed to greatly reduce the chance of exhaust leaks. The compact, low-mass design also contributes to better thermal efficiency.

Installation is straightforward because it's a direct-fit part, meaning no cutting or welding is required when you have the proper tools. Magnaflow includes essential components like a flange gasket and flat ring gaskets to help you get a proper seal during installation. This converter interchanges with OE parts like 17450-62050 and 17450-75020, making it a reliable replacement for your 4Runner.
