MagnaFlow Conv DF 08-09 Subaru STi Rear OEM

Starting with a highly corrosion-resistant 16-gauge 409 stainless steel construction, this MagnaFlow Direct-Fit Catalytic Converter is built to last. It's designed specifically to keep your check engine light off and ensure your 2008-2014 Subaru Impreza WRX STI meets Federal emissions standards. The free-flowing, mandrel-bent tubing is key here; it eliminates restrictions that can choke performance and fuel efficiency, while the compact, low-mass design helps it reach optimal thermal efficiency quickly.

MagnaFlow uses advanced 3D scanning during their research and development to ensure this converter fits and functions exactly like the original equipment. This means you get an OE-sized fit with barbed exhaust hangers made from durable 410 stainless steel, and a single laser fusion weld that significantly reduces the chance of exhaust leaks. Installation is straightforward, with no cutting or welding required, and it comes with the necessary donut and flange gaskets to get a proper seal right out of the box.

This converter is EPA-compliant for OBDII Federally registered vehicles, meaning it meets legal standards for emissions control. While it's designed to replicate factory flow dynamics and maintain original performance, it's important to note that this part is not CARB approved and cannot be shipped to California.
