MagnaFlow CARB Direct-Fit Catalytic Converter - Nissan Altima / Maxima 2007-2014

This is MagnaFlow's California Grade converter, tested to California Air Resources Board guidelines for legal use in California and CARB restricted states on the vehicles in the chart. The spun body is 16 gauge 409 stainless with mandrel-bent tubing and 308 stainless MIG welds, and a single laser fusion weld replaces the multi-pass seams that usually leak first. Its compact low-mass construction reaches operating temperature quickly, which is what keeps the downstream O2 readings in range and the check engine light off. OE-sized barbed 410 stainless hangers control noise and vibration, and hardware is included so corroded factory fasteners can be discarded.
