# MagnaFlow 51532 Direct Fit OEM Grade Catalytic Converter for 2001-2005 Buick Century 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: 51532 - Product type: Direct Fit OEM Grade Catalytic Converter - Designed for compatible vehicle applications listed on this page ### Vehicle Fitment - 2001 Buick Century, Note: Custom, Limited; 3.1L - 2002 Buick Century, Note: Custom, Limited; 3.1L - 2003 Buick Century, Note: Custom, Limited; 3.1L - 2004 Buick Century, Note: Custom, Limited; 3.1L - 2005 Buick Century, Note: Custom, Limited, Special Edition; 3.1L - 2001 Chevrolet Impala, Note: Base; 3.4L - 2002 Chevrolet Impala, Note: Base; 3.4L - 2003 Chevrolet Impala, Note: Base; 3.4L ### 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 51532. **Is this product designed for direct replacement?** Yes.
