Product Details

If you're working on a 2002-2004 Audi A6 with the 3.0L engine, this direct-fit catalytic converter from Magnaflow is designed to get your exhaust system back to proper working order. It's built to keep your check engine light off and ensure your vehicle meets federal emissions standards. This part is specifically for the driver's side application and is a direct replacement for the original equipment.

Magnaflow uses strong 16-gauge 409 stainless steel for the tubing, which offers excellent resistance to corrosion and helps ensure a long service life. The construction replicates the original equipment's flow dynamics, aiming to maintain factory performance and fuel efficiency. Installation is made simpler because it's a direct-fit design, meaning no cutting or welding is required, and it uses a single laser fusion weld to minimize the chance of leaks. The compact, low-mass design also helps with thermal efficiency.

This converter is designed to meet or exceed EPA requirements for OBDII federally registered vehicles. Please note that this part is not CARB approved and cannot be shipped to California. It interchanges with OE parts 4B0 253 011 FX and 4B0 253 011 QX.
