The MagnaFlow 49446 is a direct-fit rear catalytic converter for GM SUVs and crossovers with the 3.6L V6. It uses a spun body with a single laser-fusion weld, mandrel-bent stainless tubing and included gaskets and hardware, so it bolts on without cutting or welding. It is EPA federal-compliant, not California CARB-approved, so check your emissions status before buying. Against universal-fit converters it costs more but saves fabrication time and leak risk; against OE parts it is the lower-cost replacement that mimics the original fit.

Owners of GM 3.6L SUVs report the 49446 bolts up like the factory part and clears the check engine light. Some note fit varies by model year and that rusted factory hardware can make the job longer than expected.
This is a direct-fit replacement catalytic converter for the rear position on GM SUVs with the 3.6L engine. It is OEM grade and designed to meet or exceed Federal EPA emissions requirements. It complies with legal standards for OBDII Federally registered vehicles with California or Federal/EPA emission systems.
The converter has a stainless steel spun body that replicates the original equipment design, with mandrel-bent tubing and a single laser fusion weld. The compact, low-mass design allows for greater thermal efficiency. 3D scanning was used during development to match the fit and function of the original part.
It installs with the proper tools and requires no cutting or welding. Gaskets and hardware are included, so corroded factory parts do not need to be reused.
