MagnaFlow Conv DF 00-03 Audi A6 Quattro 4.2L Driver Side *NOT FOR SALE IN CALIFORNIA*

If you're working on a 2000-2004 Audi A6 Quattro with the 4.2L engine, or a 2002-2003 Audi S6, and need to replace the driver side catalytic converter, this Magnaflow direct-fit unit is a solid option. It's designed to meet Federal emissions requirements, helping you keep that check engine light off and your vehicle running cleanly.

Magnaflow builds this converter with strong 16-gauge 409 stainless steel tubing for good corrosion resistance, which means it should hold up well over time. The tubing is mandrel-bent to match the original equipment's shape and flow, so you can expect it to perform like the factory part. They also use a single laser fusion weld on the spun body design, which helps prevent leaks. The compact, low-mass design is also intended for better thermal efficiency.

Because this is a direct-fit converter, it's made to bolt right up to your existing exhaust system, meaning no cutting or welding is needed for installation, just the proper tools. Magnaflow uses 3D scanning during their development process to ensure the part fits correctly, just like the original equipment.
