MagnaFlow part 5582357 is a California Grade CARB compliant manifold catalytic converter, meaning it mounts in the primary, close coupled position at the exhaust manifold rather than downstream. The body uses high strength 16 gauge 409 stainless steel tubing with durable 308 stainless MIG welds, mandrel bent to eliminate flow restrictions and hold OEM geometry so factory performance and fuel efficiency carry over. MagnaFlow developed the part with 3D scanning in its metrology department so it fits and functions like the original equipment, and installation needs only the proper tools, with no cutting or welding. It carries CARB Executive Order D-193-199 and is legal for use in California and other CARB restricted states on the listed vehicles. Overall length is 28.75 in with a 7.25 in converter body and one oxygen sensor port, and a flange gasket and outlet mounting ring are included.
