# MagnaFlow 51656 Universal OEM Grade Catalytic Converter (2.5" ID/2.5" OD) for 2000-2024 Acura Ilx 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: 51656 - Product type: Universal OEM Grade Catalytic Converter (2.5" ID/2.5" OD) - Designed for compatible vehicle applications listed on this page ### Vehicle Fitment - 2013 Acura Ilx, Note: Base; 2.4L; 2.50"; 2.50" - 2014 Acura Ilx, Note: Base; 2.4L; 2.50"; 2.50" - 2015 Acura Ilx, Note: Base; 2.4L; 2.50"; 2.50" - 2007 Acura Mdx, Note: Base; 3.7L; 2.50"; 2.50" - 2008 Acura Mdx, Note: Base; 3.7L; 2.50"; 2.50" - 2009 Acura Mdx, Note: Base; 3.7L; 2.50"; 2.50" - 2010 Acura Mdx, Note: Base; 3.7L; 2.50"; 2.50" - 2011 Acura Mdx, Note: Base; 3.7L; 2.50"; 2.50" ### 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 51656. **Is this product designed for direct replacement?** Yes.
