FLOWMASTER – 50 STATE LEGAL SEMI-UNIVERSAL CATALYTIC CONVERTER

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 Semi-Universal Catalytic Converter and go back in for a retest. Since installing a new converter from any car dealer is exceedingly expensive, using a Flowmaster is a much better alternative.
