# MagnaFlow 21-457 OEM Grade Direct Fit Catalytic Converter for 2012-2019 Dodge Ram 1500 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: 21-457 - Product type: OEM Grade Direct Fit Catalytic Converter - Designed for compatible vehicle applications listed on this page ### Vehicle Fitment - 2012 Dodge Ram 1500, Note: Tradesman Hd; 5.7L - 2012 Dodge Ram 2500, Note: Laramie, Laramie Longhorn, Outdoorsman, Power Wagon, Slt, St; 5.7L - 2013 Dodge Ram 2500, Note: Big Horn, Laramie, Laramie Longhorn, Lone Star, Outdoorsman, Power Wagon, Slt, St, Tradesman; 5.7L - 2014 Dodge Ram 2500, Note: Big Horn, Laramie, Laramie Limited, Laramie Longhorn, Lone Star, Outdoorsman, Power Wagon, Slt, Tradesman; 5.7L, 6.4L - 2015 Dodge Ram 2500, Note: Big Horn, Laramie, Laramie Limited, Laramie Longhorn, Lone Star, Outdoorsman, Power Wagon, Slt, Tradesman; 5.7L, 6.4L - 2016 Dodge Ram 2500, Note: Big Horn, Laramie, Laramie Longhorn, Limited, Lone Star, Outdoorsman, Power Wagon, Slt, Tradesman; 5.7L, 6.4L - 2017 Dodge Ram 2500, Note: Big Horn, Laramie, Laramie Longhorn, Limited, Lone Star, Power Wagon, Slt, Tradesman; 5.7L, 6.4L - 2018 Dodge Ram 2500, Note: Big Horn, Laramie, Laramie Longhorn, Limited, Lone Star, Power Wagon, Slt, Tradesman; 5.7L, 6.4L ### 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 21-457. **Is this product designed for direct replacement?** Yes.
