Audi A6 Quattro Catalytic Converter - MagnaFlow - Direct Fit - `00-`01. This MagnaFlow OEM-grade direct-fit catalytic converter (part 51964) is engineered to replace the factory unit on 2000–2001 Audi A6 Quattro models, restoring emissions control and correct fitment.
Built to match OEM flow dynamics, this Federal/EPA-compliant converter is manufactured with highly corrosion-resistant stainless steel and mandrel-bent tubing to minimize flow restrictions. The spun-body design and single laser fusion weld reduce leak points while maintaining compact, low-mass construction for efficient thermal performance. MagnaFlow’s metrology-driven development uses modern 3D scanning to replicate OE geometry, helping ensure straightforward installation without cutting or welding. Gaskets and essential hardware are included to help prevent exhaust leaks and simplify replacement.
