Product Details

MagnaFlow is well-known for making exhaust components that flow well and last a long time. This direct-fit catalytic converter is built specifically for your 2004-2006 Audi S4, helping you keep that check engine light off and stay compliant with emissions regulations, especially in California and other CARB-restricted states.

This converter uses free-flowing, mandrel-bent tubing and is constructed from highly corrosion-resistant stainless steel, so it's built to handle the elements and last. MagnaFlow uses advanced 3D scanning during their research and development to ensure this part fits and functions just like the original equipment. The design replicates the OE spun body, and a single laser fusion weld is used to greatly reduce the chance of leaks. Its compact, low-mass design also helps with thermal efficiency.

Installation is made easier because this is a direct-fit unit, meaning no cutting or welding is required, and it comes with the necessary gaskets and hardware. This converter meets or exceeds California Air Resource Board (CARB) requirements and has undergone additional testing to ensure legal use in California and other CARB-restricted states.
