GMC Acadia Catalytic Converter - Magnaflow - Direct Fit - `09-`16 is a MagnaFlow OEM-grade direct-fit catalytic converter (MagnaFlow PN 51579) engineered for 2009–2016 GMC Acadia applications. It offers a direct replacement intended to match factory fit and flow characteristics without cutting or welding.
This converter uses a replicated OE spun-body design with a single laser fusion weld to reduce leak points and a compact, low-mass construction for efficient thermal performance. Mandrel-bent tubing and highly corrosion-resistant stainless steel help preserve exhaust flow and resist corrosion over time. The unit is supplied with gaskets and hardware to minimize the chance of a leaking seal and avoid reusing corroded factory parts. Designed to meet federal EPA emissions requirements, it also interchanges with OE part numbers 19418968 and 20906951.
