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

When your Audi A6 Quattro from 2000-2004 needs a new catalytic converter, this direct-fit unit from Magnaflow is a solid option. It's designed specifically for the passenger side of your 4.2L engine, and it's built to keep your check engine light off by meeting Federal emissions requirements. This converter is compliant with EPA standards for OBDII Federally registered vehicles.

You get a well-built converter that uses free-flowing, mandrel-bent tubing for optimal exhaust flow, which helps maintain factory performance and fuel efficiency. The construction features a durable 16-gauge 409 stainless steel body for excellent corrosion resistance and a long service life. Magnaflow replicates the original equipment's spun body design, and a single laser fusion weld is used to greatly reduce the chance of leaks. This compact, low-mass design also contributes to better thermal efficiency. Installation is made simpler because essential gaskets and hardware are included in the box, and because it's a direct-fit part, there's no cutting or welding required – just use the proper tools.

This Magnaflow converter interchanges with OE part numbers like 4B3 254 550 CX and 4B3 254 550 GX. Please note that this part is not for sale in California due to emissions regulations.
