MagnaFlow Conv DF Audi 97-05 A4/A4 Quattro / Volkwagen 00-05 Passat 1.8L

When your check engine light comes on, and you suspect it's your catalytic converter, MagnaFlow's Direct-Fit Catalytic Converter 51644 is what you'll want to get your Audi A4 or Volkswagen Passat back to running right. This unit comes with everything you need to get the job done, including two flange gaskets to ensure a proper seal, so you can be confident about avoiding exhaust leaks. It's built with free-flowing, mandrel-bent tubing and constructed from highly corrosion-resistant stainless steel, specifically 16-gauge 409 stainless steel for the tubing and 308 stainless steel for the welds, which means it's made to last. MagnaFlow uses advanced 3D scanning during their research and development to ensure this converter fits and functions just like the original equipment, replicating the OE spun body design with a single laser fusion weld to reduce leak possibilities. This compact, low-mass design also helps with thermal efficiency.

This direct-fit converter is designed to meet or exceed Federal emissions requirements set forth by the EPA, making it compliant for OBDII Federally registered vehicles with California or Federal/EPA Emission systems. Installation is straightforward, as it's designed to bolt directly in place of your original converter, meaning no cutting or welding is required, just the proper tools. It's a solid option for your 1997-2005 Audi A4 Quattro, 1997-2006 Audi A4, or 1998-2005 Volkswagen Passat 1.8L.
