MagnaFlow Conv DF 00-02 Audi S4 2.7L P/S

When it's time to replace the catalytic converter on your 2000-2002 Audi S4, you're getting a direct-fit unit from MagnaFlow, part number 49916. This converter is designed to meet Federal emissions requirements set forth by the EPA, helping you keep that check engine light off and your vehicle running cleanly. It's built to work with OBDII Federally registered vehicles that have California or Federal/EPA Emission systems.

What you get in the box is a well-built catalytic converter, complete with a flange gasket to ensure a proper seal during installation. The tubing is mandrel-bent, which means it maintains its diameter throughout the bend, helping to replicate the original equipment's flow dynamics and keep your factory performance and fuel efficiency intact. The converter itself features a spun body design, and MagnaFlow uses a single laser fusion weld, which significantly reduces the chance of exhaust leaks. The construction uses high-strength 16-gauge 409 stainless steel for the tubing, offering excellent resistance to corrosion and a long service life. The welds are durable 308 stainless steel Mig welds.

This converter is designed for an easy installation, meaning no cutting or welding is required, and it uses the proper tools. MagnaFlow uses advanced 3D scanning during their research and development to ensure this part fits and functions just like the original equipment it replaces. This converter interchanges with OE part number 8E0 253 058 BX.
