MagnaFlow's California Grade converter is a CARB compliant replacement for the passenger side converter on the 3.7L V6 and bolts into the factory location without cutting or welding. A 2.25 in flange inlet feeds a 3 in flange outlet across a 50 in assembly with a 9.25 in round spun bed, and the 16 gauge 409 stainless steel tubing is joined with 308 stainless steel MIG welds over a ceramic substrate. Two ports serve the pre converter and midbed oxygen sensors, and OE sized barbed 410 stainless steel hangers ship alongside a Torca AccuSeal clamp. CARB Executive Order D-193-197 makes it legal for installation in all 50 states.
