MagnaFlow California Grade Direct-Fit Catalytic Converter - Jeep Liberty 3.7L 2004 - 4551582

MagnaFlow's California Grade converter replaces the factory Y collector converter assembly on the 3.7L V6 as a CARB compliant bolt-in unit, so no cutting or welding is required. Two inlets gather both banks into a single 2.5 in outlet across a 54.375 in assembly, with 16 gauge 409 stainless steel tubing, 308 stainless steel MIG welds, and a spun body over a ceramic substrate. Two ports are provided for the pre and post converter oxygen sensors, and OE sized barbed 410 stainless steel hangers plus Torca AccuSeal clamps ship in the box. CARB Executive Order D-193-184 makes it legal for installation in all 50 states.
