Audi A6 Catalytic Converter - Magnaflow - Direct Fit - `06-`09. A direct-fit replacement catalytic converter engineered for 2006–2009 Audi A6 models, offering CARB-compliant emissions performance and OE-style fitment.
This Magnaflow direct-fit converter replicates the factory spun-body design and is built with mandrel-bent tubing and corrosion-resistant stainless steel to match original flow dynamics. The unit is designed to install without cutting or welding when using the supplied gaskets and hardware, reducing install time and the risk of exhaust leaks. It interchanges with OE part 4A0 253 057 EX and is engineered to meet California Air Resources Board requirements for the listed applications when the converter’s Executive Order and Engine Family numbers correspond to the vehicle. Single laser fusion welds and a compact, low-mass configuration help maintain thermal efficiency and reliable sealing at the joint.
