# MagnaFlow 51366 OEM Grade Universal Catalytic Converter (2.50" ID/2.50" OD) for 2009-2023 Cadillac Escalade 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: 51366 - Product type: OEM Grade Universal Catalytic Converter (2.50" ID/2.50" OD) - Designed for compatible vehicle applications listed on this page ### Vehicle Fitment - 2021 Cadillac Escalade, Note: Luxury, Premium Luxury, Premium Luxury Platinum, Sport, Sport Platinum; 6.2L - 2022 Cadillac Escalade, Note: Luxury, Premium Luxury, Premium Luxury Platinum, Sport, Sport Platinum; 6.2L - 2023 Cadillac Escalade, Note: Luxury, Premium Luxury, Premium Luxury Platinum, Sport, Sport Platinum; 6.2L - 2021 Cadillac Escalade Esv, Note: Luxury, Premium Luxury, Premium Luxury Platinum, Sport, Sport Platinum; 6.2L - 2022 Cadillac Escalade Esv, Note: Luxury, Premium Luxury, Premium Luxury Platinum, Sport, Sport Platinum; 6.2L - 2023 Cadillac Escalade Esv, Note: Luxury, Premium Luxury, Premium Luxury Platinum, Sport, Sport Platinum, V; 6.2L - 2021 Chevrolet Suburban, Note: High Country; 6.2L - 2022 Chevrolet Suburban, Note: High Country, Premier, Rst, Z71; 6.2L ### 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 51366. **Is this product designed for direct replacement?** Yes.
