MagnaFlow Conv DF 00-02 Audi A6 Quattro 2.7L

When your check engine light comes on and you suspect a catalytic converter issue, MagnaFlow's Direct-Fit Catalytic Converter (part number 23643) is a solid option for your 2000-2002 Audi A6 Quattro. This unit is designed to meet Federal emissions requirements set by the EPA, ensuring your vehicle stays compliant with OBDII standards for federally registered vehicles. You'll receive the converter itself, along with a flange gasket to help ensure a proper seal during installation, which is crucial for preventing exhaust leaks.

MagnaFlow builds this converter with free-flowing, mandrel-bent tubing and a spun body design that replicates the original equipment's shape and flow dynamics. This helps maintain your car's factory performance and fuel efficiency. The construction uses high-strength 16-gauge 409 stainless steel tubing for excellent corrosion resistance, and the single laser fusion weld is designed to minimize leak possibilities. The compact, low-mass design also contributes to better thermal efficiency.

Because this is a direct-fit unit, it's designed to install without cutting or welding, making the job much simpler if you're doing it yourself. MagnaFlow uses advanced 3D scanning in their R&D process to ensure the part fits and functions like the original. This converter interchanges with OE parts 4B0 253 011 X and 4B0 253 057 HX.
