# MagnaFlow 51509 Universal OEM Grade Catalytic Converter (3" ID/3" OD) for 1996-2007 Chevrolet C2500 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: 51509 - Product type: Universal OEM Grade Catalytic Converter (3" ID/3" OD) - Designed for compatible vehicle applications listed on this page ### Vehicle Fitment - 1996 Chevrolet C2500, Note: Base, Cheyenne, Silverado; 5.7L; 3.00"; 3.00" - 1997 Chevrolet C2500, Note: Base, Cheyenne, Silverado; 5.7L; 3.00"; 3.00" - 1998 Chevrolet C2500, Note: Base, Cheyenne, Silverado, Wt; 5.7L; 3.00"; 3.00" - 1999 Chevrolet C2500, Note: Base, Ls; 5.7L; 3.00"; 3.00" - 2000 Chevrolet C2500, Note: Base, Ls; 5.7L; 3.00"; 3.00" - 1996 Chevrolet C3500, Note: Base, Cheyenne, Silverado; 5.7L; 3.00"; 3.00" - 1997 Chevrolet C3500, Note: Base, Cheyenne, Silverado; 5.7L; 3.00"; 3.00"; 131.5 In.
