Product Details

When it's time to replace the catalytic converter on your 2011 or 2012 Audi A8 Quattro with the 4.2L V8 engine, this Magnaflow Direct-Fit converter is a solid option. You'll get the converter itself, along with two flange gaskets, three nuts, and three bolts to help with installation. This part is designed to meet Federal emissions requirements set by the EPA, making it compliant for OBDII Federally registered vehicles. It's built with highly corrosion-resistant stainless steel tubing and features free-flowing mandrel-bent construction to maintain factory performance and fuel efficiency.

Magnaflow uses advanced 3D scanning during their research and development to ensure this converter fits just like the original equipment. The single laser fusion weld is designed to reduce the chance of leaks, and its compact, low-mass design helps with thermal efficiency. Because it's a direct-fit unit, you won't need to cut or weld anything during installation, simplifying the process. Just be aware that this converter is not CARB approved and cannot be shipped to California.
