# MagnaFlow 51098 Direct Fit OEM Grade Catalytic Converter (2.25" ID/2.25" OD) for 2003-2008 Infiniti Fx35 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: 51098 - Product type: Direct Fit OEM Grade Catalytic Converter (2.25" ID/2.25" OD) - Designed for compatible vehicle applications listed on this page ### Vehicle Fitment - 2003 Infiniti Fx35, Note: Base; 3.5L; 2.25"; 2.25"; Rear Wheel Drive - 2004 Infiniti Fx35, Note: Base; 3.5L; 2.25"; 2.25"; Rear Wheel Drive - 2005 Infiniti Fx35, Note: Base; 3.5L; 2.25"; 2.25"; Rear Wheel Drive - 2006 Infiniti Fx35, Note: Base; 3.5L; 2.25"; 2.25"; Rear Wheel Drive - 2007 Infiniti Fx35, Note: Base; 3.5L; 2.25"; 2.25"; Rear Wheel Drive - 2008 Infiniti Fx35, Note: Base; 3.5L; 2.25"; 2.25"; Rear Wheel Drive - 2003 Infiniti G35, Note: Base; 3.5L; 2.25"; 2.25" - 2004 Infiniti G35, Note: Base; 3.5L; 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 51098. **Is this product designed for direct replacement?** Yes.
