MagnaFlow Conv DF Audi 00-04 A6 Quattro 02-03 S6 4.2L Driver Side *NOT FOR SALE IN CALIFORNIA*

The single laser fusion weld on this MagnaFlow catalytic converter is designed to greatly reduce the chance of leaks, a common issue with exhaust components. This driver-side converter is built for the 2000-2004 Audi A6 Quattro and the 2002-2003 Audi S6 with the 4.2L engine. It's constructed with highly corrosion-resistant stainless steel tubing, specifically 16-gauge 409 stainless steel for the tubing and 308 stainless steel for the welds, ensuring a long service life even in harsh conditions.

MagnaFlow uses advanced 3D scanning during their research and development to ensure this converter fits and functions just like the original equipment. The free-flowing, mandrel-bent tubing is shaped to maintain factory performance and fuel efficiency, while the compact, low-mass design helps with thermal efficiency. Because it's a direct-fit unit, installation is simplified as it uses the OE mounting points, meaning no cutting or welding is required, just the proper tools. This converter is EPA-compliant and meets Federal emissions requirements for OBDII vehicles with Federal/EPA emission systems, helping to keep your check engine light off.

Please note that this converter is not for sale in California due to emissions regulations. It interchanges with OE parts like 4B3 254 500 GX and 4B3 254 500 CX.
