MagnaFlow OEM Grade Direct-Fit Catalytic Converter 51231 for 2010-2015 Toyota 4Runner, 2010-2014 FJ Cruiser, Stainless Steel

Why This Converter Rocks

So, if you're looking to keep that check engine light from ruining your day, the MagnaFlow OEM Grade Direct-Fit Catalytic Converter 51231 is a solid choice. This thing is built from tough stainless steel, which means it can handle the heat and the elements without falling apart on you. Plus, it’s designed to fit your 2010-2015 Toyota 4Runner or 2010-2014 Toyota FJ Cruiser like a glove—no cutting or welding required.

What I love about this converter is the way it’s crafted. The free-flowing mandrel-bent tubing really helps your exhaust system breathe better, and that’s crucial for performance. MagnaFlow’s team uses some fancy 3D scanning tech during their R&D, so you can trust that this part will fit and function just like the original. They’ve even replicated the OE spun body design, which means fewer leaks thanks to a single laser fusion weld. It’s compact too, which helps with thermal efficiency—always a bonus.

Specs That Matter

• Material: Tough stainless steel that resists corrosion.
• Overall Length: 26.5 inches—just the right size.
• Main Piping Diameter: 2.25 inches for optimal flow.
• Oxygen Sensor Location: Pre-converter, so you won’t have to mess with it.
• Mounting Hardware? Yep, it’s included.

When you install this bad boy, make sure to use the gaskets provided to avoid any exhaust leaks. And just a heads up, this converter meets or exceeds the Federal emissions standards set by the EPA, which is a must if you want to stay legal.
