The MagnaFlow 51205 is a universal-fit catalytic converter with a 2.25-inch inlet and outlet, built from stainless steel for corrosion resistance. It is a 49-state unit, so it is not legal for sale or use in California or on California-registered vehicles. It suits drivers replacing a failed converter on an older car or truck who can weld or clamp a universal part in place. Unlike direct-fit converters, it needs fabrication to match the factory pipe, so it is cheaper than a bolt-on replacement but demands more install work.
