# MagnaFlow 51355 Universal OEM Grade Catalytic Converter (2.25" ID/2.25" OD) for 1999-2023 Audi A4 and More ### Performance Overview The Magnaflow OEM Grade Catalytic Converters are the perfect replacement for your stock converter. They are crafted from high-quality stainless or aluminized steel for maximum durability. They are seam-welded for unbreakable bonds with no risk of vibrations. The catalytic converters are available with a lap inserted in the point where the neck meets the catalytic converter body. The neck is carefully formed to be sure that it doesn't reach the body where it can cause trouble to the exhaust flow. As an additional safety feature, the Catalytic Converter has a heavy duty heat shield to protect it against extreme heat and give additional stability. ### Key Features - Brand: MagnaFlow - Part number: 51355 - Product type: Universal OEM Grade Catalytic Converter (2.25" ID/2.25" OD) - Designed for compatible vehicle applications listed on this page ### Vehicle Fitment - 2002 Audi A4, Note: Base; 3.0L; 2.25"; 2.25"; Automatic Trans - 2003 Audi A4, Note: Base; 3.0L; 2.25"; 2.25"; Automatic Trans - 2004 Audi A4, Note: Base; 3.0L; 2.25"; 2.25"; Automatic Trans - 2002 Audi A4 Quattro, Note: Avant, Base; 3.0L; 2.25"; 2.25" - 2003 Audi A4 Quattro, Note: Avant, Base; 3.0L; 2.25"; 2.25" - 2004 Audi A4 Quattro, Note: Avant, Base, Cabriolet; 3.0L; 2.25"; 2.25" - 2005 Audi A4 Quattro, Note: Avant, Base; 3.0L, 3.2L; 2.25"; 2.25"; Manual Trans - 2006 Audi A4 Quattro, Note: Avant, Base; 3.2L; 2.25"; 2.25" ### FAQ **Will this fit my vehicle?** Please verify your year, make, model, position, and any fitment notes using the compatibility list above before purchase. **What part number is this?** The listed part number is 51355. **Is this product designed for direct replacement?** Yes.
