Magnaflow 11-12 A8 Quattro V8 4.2 OEM Close Coupled Direct Fit Converter

You're getting a Magnaflow Direct-Fit Catalytic Converter, part number 21-695, designed specifically for the 2011-2012 Audi A8 Quattro with the 4.2L V8 engine. This kit includes everything you need for installation: three nuts, two flange gaskets, and three bolts. It's built to meet Federal emissions requirements set by the EPA for OBDII Federally registered vehicles, ensuring your check engine light stays off and your car runs cleanly.

This converter is constructed with high-strength 16-gauge 409 stainless steel tubing, which is highly resistant to corrosion and built for a long service life. Magnaflow uses advanced 3D scanning during their research and development to ensure this part replicates the original equipment's fit and function precisely. The tubing is mandrel-bent to maintain the original design and geometry, and the compact, low-mass design helps with thermal efficiency. A single laser fusion weld is used to greatly reduce the possibility of leaks, and the durable 308 stainless steel MIG welds add to its solid construction.

Because this is a direct-fit converter, it's designed for an easy installation with no cutting or welding required, assuming you have the proper tools. It's important to note that this converter is not CARB approved and cannot be shipped to California. It interchanges with OE parts 4H0 254 250 NX and 4H0 254 250 QX.
