This is MagnaFlow's California Grade converter, tested to California Air Resources Board guidelines for legal use in California and CARB restricted states on the vehicles in the chart. The spun body is 16 gauge 409 stainless with mandrel-bent tubing and 308 stainless MIG welds, replicating OE geometry so exhaust flow and fuel economy stay where the factory set them. OE-sized barbed 410 stainless hangers control noise and vibration, and the supplied Torca AccuSeal clamps apply even clamping force around the full circumference so the pipe does not distort when torqued. Gaskets and hardware are included, and no cutting or welding is required.
