This MagnaFlow OEM-grade rear catalytic converter is a Federal/EPA compliant direct-fit replacement for 2009-2010 Kia Optima models.

Built using MagnaFlow's production standards and metrology, this direct-fit converter replicates OE spun-body geometry to maintain factory flow dynamics and reduce the risk of leaks. The unit features mandrel-bent tubing and high-strength 16 gauge 409 stainless steel for corrosion resistance and service life. A single laser fusion weld and compact, low-mass design support consistent thermal performance. The part ships with the necessary gaskets and hardware to simplify installation and is identified as MagnaFlow part 51714, interchanging with OE numbers 28950-2G310 and 28960-2G540.
