MagnaFlow CARB Rear Right Secondary Catalytic Converter - Nissan Pathfinder / Infiniti QX4 2001-2004

This is the rear right, passenger side secondary converter for the 3.5L V6, one of four converters on this vehicle, so check the position before ordering. The clam-shell body replicates the OE part and bolts into the factory location with no cutting or welding. The tubing is 16 gauge 409 stainless mandrel bent to hold the OE flow geometry, joined by a single laser fusion weld that leaves fewer seams to leak, with 308 stainless MIG welds and OE-sized barbed 410 stainless hangers to keep noise and vibration down. A single oxygen sensor port sits pre converter, and the part is CARB compliant under Executive Order D-193-176 for legal installation in California and the CARB restricted states. A crush ring gasket and a flange gasket are included.
