The MagnaFlow California Grade direct-fit catalytic converter 441057 is a CARB-compliant replacement engineered to match OE flow and emissions performance for select Subaru applications. Mandrel-bent tubing and corrosion-resistant stainless steel reduce flow restrictions and resist corrosion, while the spun-body design and laser fusion weld lower leak potential. Includes gaskets and hardware for a no-cut, no-weld install on 2002–2006 Subaru Impreza applications.
