Product Details

The Flowmaster 50 Series Delta Flow Chambered Muffler delivers performance exhaust sound with significantly reduced interior resonance, making it an ideal choice for street rods, sport trucks, and daily-driven performance vehicles. This muffler features a 3-chamber design that utilizes Delta Flow technology to produce a mellow, deep sound while maintaining excellent flow characteristics.

Key Features:

  • Constructed of 16-gauge 409S stainless steel with fully MIG-welded seams for maximum durability
  • 2.5-inch inlet and 2.5-inch outlet configuration
  • Offset inlet with center outlet positioning
  • Oval body measuring 17 inches long x 9.75 inches wide x 4 inches tall
  • 23-inch overall length including inlet/outlet pipes
  • Milder exterior tone than 40 Series mufflers and significantly quieter on the inside
  • Provides the same performance and exterior tone as two-chamber designs with less interior resonance

The Delta Flow technology manages exhaust flow through internal deflectors and a tuning chamber, producing a moderate exterior tone while virtually eliminating the droning and resonance often experienced inside the cabin. This makes the 50 Series an excellent upgrade for enthusiasts who want performance gains and enhanced sound without excessive noise during highway cruising.

Performance Benefits: The three-chamber Delta Flow design improves exhaust scavenging, resulting in increased horsepower, torque, and overall engine efficiency. The black stainless steel finish resists corrosion and oxidation for long-lasting performance and appearance.
