Flowmaster 50-State Legal Semi-Universal Catalytic Converter

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. After installing a Flowmaster 50 State Legal Semi-Universal Catalytic Converter, your car, truck or SUV will have a much better chance of passing the smog test and it will not trip check engine lights as well. Flowmaster known as ‘the exhaust technology company,’ is a leading manufacturer of high performance exhaust systems and respected for design, innovation and engineering.

  • Great for replacing worn out factory original catalytic converters
  • Designed and manufactured in U.S.A.
