Show original supplier description
The MagnaFlow 52594-AP is a direct-fit catalytic converter engineered to maintain emissions compliance and prevent check engine lights on compatible vehicles. The use of state-of-the-art 3D scanning in its development ensures an exact fit, simplifying installation for DIYers as no cutting or welding is necessary. The converter features a compact, low-mass design for optimal thermal efficiency and a single laser fusion weld to minimize leak possibilities. It includes necessary hardware such as nuts, bolts, and flat washers for installation and is designed with two sensor ports to accommodate pre and post-converter oxygen sensors. This catalytic converter is Federal EPA compliant. It is explicitly not legal for sale or installation in California, Colorado, or New York. It is designed for use on 2000 model year and earlier vehicles or any model year vehicle manufactured with EPA or Federal emissions non-50-State certification. Specifically, it fits the Buick LaCrosse (2012-2015) with V6 3.6L engines, the Cadillac XTS (2013-2019) with V6 3.6L engines, and the Chevrolet Impala (2014-2020) with V6 3.6L engines.
