MagnaFlow CARB Rear Secondary Catalytic Converter - Nissan Maxima / Infiniti I35 2002-2004

This is the downstream secondary converter for the 3.5L V6, built on a clam-shell body that replicates the OE part so it 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. It is CARB compliant under Executive Order D-193-171, which makes it legal to install in California and the CARB restricted states on the listed vehicles, and two flange gaskets come in the box.
