A direct-fit replacement catalytic converter for the 2009-2017 Chevrolet Traverse, 2007-2016 GMC Acadia and other GM Lambda-platform vehicles. It uses a stainless steel spun body with mandrel-bent tubing, a single laser fusion weld and included gaskets and hardware, so it bolts on without cutting or welding. It is Federal/EPA compliant, not California CARB approved, so check your state's rules before buying. Against universal-fit converters it costs more but fits like the original and avoids fabrication; owners of these aging crossovers pick it to clear a P0420 code and pass emissions inspection.

Owners of Traverse and Acadia models generally report a clean fit and that the check engine light stays off after installation. Complaints center on the narrow vehicle fitment and the fact that it cannot be used in California.
The MagnaFlow OEM Grade 49445 is a direct-fit catalytic converter built to meet or exceed Federal emissions requirements set by the EPA. It complies with legal standards for OBDII Federally registered vehicles with California or Federal/EPA emission systems. It is designed to fit the 2009-2017 Chevrolet Traverse, 2007-2016 GMC Acadia, and additional vehicles.
The converter has a spun stainless steel body and stainless steel mandrel-bent tubing. It replicates the OE spun body design, and a single laser fusion weld reduces the possibility of a leak. The compact, low-mass design allows for greater thermal efficiency. MagnaFlow used 3D scanning during development so the part fits and functions like the original equipment.
Installation needs no cutting or welding and can be done with the proper tools. Gaskets and hardware are included, so corroded factory parts do not need to be reused.
