MagnaFlow 5531293 is a direct-fit manifold catalytic converter that replaces the factory exhaust manifold and close-coupled converter as a single bolt-in assembly, with no cutting or welding required. The spun stainless steel body houses a ceramic substrate, measures 19 in overall with a 3.25 in converter body, and uses flanged inlet and outlet connections plus one sensor port. High strength 16 gauge 409 stainless steel tubing is mandrel bent to retain OE flow geometry, and 308 stainless steel MIG welds resist corrosion. It is CARB certified under Executive Order D-193-175 for legal installation in California and CARB states, and ships with the gaskets and hardware needed to fit it.
