MagnaFlow 4593218 is the California Grade replacement for the driver side downstream converter, a spun body direct-fit unit built from 16 gauge 409 stainless steel with a ceramic substrate and a single laser fusion weld that limits leak paths. It measures 29 inches overall, carries one oxygen sensor port ahead of the catalyst and no air tube, and bolts up at both flanges with no cutting or welding. CARB Executive Order D-193-188 covers it for registered use in California and the other CARB states. One flange gasket, one crush ring, two washers, two bolts and two nuts ship in the box, so corroded factory hardware does not have to be reused.
