MagnaFlow Conv DF 03-04 Audi RS6 4.2L Passenger Side

This is the passenger side, direct-fit catalytic converter from Magnaflow, part number 24501. It's designed specifically for your 2003 Audi RS6 with the 4.2L engine. This converter is built to keep your check engine light off by meeting Federal emissions requirements set by the EPA for OBDII federally registered vehicles. You'll get the converter, along with essential gaskets and hardware needed for installation, right in the box.

Magnaflow uses high-strength 16-gauge 409 stainless steel tubing for excellent corrosion resistance and a long service life. The tubing is mandrel-bent for free-flowing exhaust gases, helping to maintain factory performance and fuel efficiency. They've replicated the original equipment's spun body design, and the single laser fusion weld is designed to greatly reduce the chance of leaks. This compact, low-mass design also helps with thermal efficiency. Magnaflow uses 308 stainless steel for its MIG welds, further ensuring durability.

Because this is a direct-fit unit, it's designed to install easily without any cutting or welding, using the proper tools. It's a well-built replacement that interchanges with the original equipment part number 4B3 253 058 EX. Please note that this converter is not CARB approved and cannot be shipped to California.
