Product Details

The Flowmaster Flow FX Muffler combines legendary Flowmaster performance with sophisticated sound control technology. This premium exhaust muffler features a high-flow straight-through design that maximizes exhaust flow for improved horsepower and throttle response, while advanced interior sound absorption material tames unwanted drone and harshness.

Key Features:

  • Straight-through design delivers maximum exhaust flow and performance gains
  • High-temperature sound absorption material reduces interior cabin noise
  • Mild to moderate interior sound level—perfect for daily driving comfort
  • Moderate exterior performance tone provides classic muscle car sound
  • Fully welded 409S stainless steel construction ensures durability and corrosion resistance
  • Bright polished finish adds a professional appearance to any exhaust system

The Flow FX series represents Flowmaster's most refined chambered muffler design, engineered for enthusiasts who want noticeable performance improvements without excessive interior noise. The straight-through internal configuration minimizes backpressure while the proprietary sound absorption technology maintains the aggressive Flowmaster tone outside the vehicle while keeping interior sound levels comfortable for passengers.
