FLOWMASTER – 50 STATE LEGAL DIRECT-FIT CATALYTIC CONVERTERS

Failed the smog test because of a malfunctioning stock catalytic converter that has come to the end of its life? Don’t panic and send your vehicle off to the junkyard when everything else is running smoothly. Replace that old catalytic converter with a new Flowmaster 50 State Legal Direct-Fit Catalytic Converter and go back in for a retest. Since installing a new converter from any car dealer is exceedingly expensive, bolting on a Flowmaster is a much better alternative.
