240 Series Stainless Steel Oval Catalytic Converter by Flowmaster®, 2.5" Inlet / 2.5" Outlet. 16.5" Length. 7.25" Width. Includes Heat Shield, 4 Bolt Flanges. The new Flowmaster replacement catalytic converters are made to meet and exceed all federal environmental regulations and, as all Flowmaster products, to deliver the best possible performance. The shells are made of stainless steel, and the catalytic components meet or exceed the legal requirements.

Notes:

  • These converters meet Federal US EPA standards. They are NOT legal for sale or use on any vehicle licensed or operated in the state of California
  • Additional sizing, bushings, cutting may be required due to OE exhaust design

Features:

  • Exceed all federal emission standards
  • Stainless Steel shells
  • High load of noble metals in substrate for reliable performance
  • Efficient gas flow
  • 25000 mile emission compliance warranty on internal components
  • 50000 mile/5 year warranty on exterior casings

Flowmaster, the masters of performance mufflers and exhaust systems since 30 years, have decided to also offer street legal, high quality, replacement catalytic converters to the market. The catalytic converters are engineered for long life and reliable performance. When you install a Flowmaster Catalytic Converter you avoid the irritation that low quality converters can cause by frequently lighting up the MIL symbol on your dash, requiring equally frequent service appointments to check the codes and make the relevant adjustments. The Flowmaster converters are engineered and built in the U.S.A., using only first grade materials, to the high quality standard required to get the Flowmaster trademark stamped into the casing.

The outer shells are made in stainless steel of the highest automotive grade. The interiors of the converters feature strata that carry catalytic substrates with high loads of noble metals, making sure that the converters perform to exceed the USEPA standards. The strata themselves are of OEM or higher quality, ensuring that they last and can endure the vibrations and stress even in hard driving conditions. As Flowmaster is the master of gas flow, you can also rest assured that the exhaust gases flow through the converters with minimum possible restrictions for maximum possible performance. If and when you need to replace your catalytic converter, get a converter with the Flowmaster stamp. There is no better.

Flowmaster® has its roots in solving the engine noise problems encountered by California racers in the 1980s. In 1983 Flowmaster’s founder, Ray Flugger, created his first patented design of racing silencers, which dampened noise with minimal loss of power. Ray attached handles to ease carrying the square shaped race mufflers through the race pits, and the mufflers became known as the "suitcase mufflers." Today, the innovative Flowmaster mufflers are the result of years of development with top race engine builders, thousands of hours of dyno research and "real-world" on-track testing.
