MagnaFlow Conv DF 03-04 4Run 4.7 Driver Side Manifold

Starting with its highly corrosion-resistant stainless steel construction, this Magnaflow direct-fit catalytic converter is built to last. It’s designed specifically for your 2003-2005 Lexus GX470 and 2003-2004 Toyota 4Runner, ensuring it keeps that check engine light off and your vehicle running cleanly.

Magnaflow uses advanced 3D scanning during their research and development to make sure this converter matches the original equipment in both fit and function. The free-flowing, mandrel-bent tubing helps maintain factory performance and fuel efficiency, while the compact, low-mass design contributes to better thermal efficiency. A single laser fusion weld replicates the OE design, significantly reducing the chance of leaks. Because it’s a direct-fit unit, installation is straightforward with no cutting or welding required, and it even comes with the necessary gaskets and hardware to avoid reusing old, corroded parts.

This converter meets Federal emissions requirements set by the EPA for OBDII federally registered vehicles. Please note that this part is not CARB approved and cannot be shipped to California.
