Product Details

The Flowmaster 50 Series HD Chambered Muffler is engineered specifically for heavy-duty truck applications, delivering enhanced performance and the signature Flowmaster sound. This chambered muffler utilizes Flowmaster's patented delta flow technology to minimize interior drone while maximizing exhaust flow and scavenging.

Key Features:

  • Heavy-duty construction designed for 6.2L Ford, 6.4L Ram, and 6.2L GM trucks
  • Chambered design produces a moderate exterior tone with mild interior resonance
  • Improves horsepower, torque, and overall engine efficiency
  • Durable aluminized steel construction for long-lasting performance
  • Direct-fit replacement with 3.5-inch inlet and outlet configuration
  • Backed by Flowmaster's lifetime limited warranty

The 50 Series HD delivers noticeable performance gains without excessive cabin noise, making it ideal for daily-driven heavy-duty trucks. The moderate sound level provides an aggressive exhaust note under acceleration while remaining civil during highway cruising.
