Product Details

The Flowmaster Flow FX Muffler delivers a balanced performance exhaust solution with moderate sound levels and minimal restriction. Engineered with a straight-through design, this muffler utilizes an internal multi-core construction that allows exhaust gases to flow efficiently while managing noise output, making it ideal for daily drivers who want enhanced performance without excessive volume.

Key Features:

  • Straight-through perforated core design for maximum flow and power gains
  • Moderate exterior exhaust tone—quieter than aggressive race mufflers, deeper than stock
  • Fully welded 409S stainless steel construction for long-lasting durability and corrosion resistance
  • Multi-core internal configuration balances sound control with performance
  • No internal packing or fiberglass to degrade over time
  • Ideal for street trucks, SUVs, and performance vehicles requiring moderate sound levels

The Flow FX series is perfect for enthusiasts who want improved exhaust flow and a deeper tone without the loud, aggressive sound of chambered or race-style mufflers. The durable stainless steel case ensures years of reliable performance in all weather conditions.
