MagnaFlow's OEM Grade direct-fit catalytic converter drops into the factory location with no cutting or welding. The spun body uses 16 gauge 409 stainless steel tubing, 308 stainless MIG welds and a single laser fusion weld that reduces leak paths, while mandrel-bent tubing preserves OE exhaust geometry. A dual inlet, dual outlet layout at 3 in each carries both banks through one 27.375 in assembly. OE-sized 410 stainless barbed hangers, Torca AccuSeal clamps and gaskets are included in the box, and the converter meets Federal EPA requirements while interchanging with OE parts 25958404, 25958405, 25958406 and 25958407.
