MagnaFlow Conv DF 04-06 Audi A8 Quattro 4.2L

If you're working on a 2004 to 2006 Audi A8 Quattro with the 4.2L engine, this direct-fit catalytic converter from Magnaflow is built to get your exhaust system back to factory specifications. It's designed to help you keep that check engine light off and ensure your vehicle complies with federal emissions standards set by the EPA. This is a crucial part for maintaining your car's performance and environmental compliance.

Magnaflow builds this converter using highly corrosion-resistant stainless steel for the tubing and a durable 308 stainless steel for the welds, meaning it's made to last. They use advanced 3D scanning during development to ensure it fits just like the original equipment, so you won't have to fight with it during installation. The mandrel-bent tubing and precision-stamped collector are designed to maintain factory flow dynamics, which helps keep your engine running efficiently and preserves your fuel economy. The single laser fusion weld is a smart detail that greatly reduces the chance of exhaust leaks, and its compact, low-mass design helps with thermal efficiency.

This converter is a direct-fit unit, meaning no cutting or welding is required for installation, making the job much simpler. It comes with a Torca clamp to help secure the connection. This part is designed to meet or exceed Federal emissions requirements for OBDII vehicles registered in states that follow Federal/EPA emission standards. Please note that this converter is not CARB approved and cannot be shipped to California.
