Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 51086. With features including free-flowing mandrel-bent tubing and highly corrosion resistant, stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. This direct-fit catalytic converter is designed specifically for the 2001-2003 Audi S8 and interchanges with OE parts 4D0 131 090 RX and 4D0 254 350 BX. Hardware is included to eliminate the hassle of working with corroded factory parts.

Worked out great
Replaced on my E46 with this, it had better finish than the original, since it had a worn coating. Fitted like OEM without the OEM price.
