Product Details

The Flowmaster Flow FX stainless steel performance muffler line gives enthusiasts a straight-through exhaust muffler with a moderate performance tone. It sounds different from the chambered note Flowmaster is known for. Flow FX is an economical way to add a sporty exhaust sound and improve exhaust flow.

Key Features:

  • Straight-through perforated core design promotes free-flowing exhaust gases and a deep, traditional, mellow tone
  • Fully welded 409S stainless steel case resists corrosion and gives long service life
  • High-temperature sound absorption material surrounds the core for good sound control
  • Moderate exterior performance tone, with a mild to moderate tone inside the vehicle
  • Compact case styles suit a wide range of exhaust setups
  • Absorption-type muffler construction
  • Flowmaster quality and craftsmanship

Flow FX mufflers suit drivers who want a performance muffler with durable stainless construction and an even sound level. Each part number in the line is offered in its own configuration, so you can match the muffler to your exhaust setup.
