Product Details

The Flowmaster 42582 80 Series Chambered Muffler delivers an aggressive exhaust tone with the original two-chamber design that made Flowmaster famous. Engineered for cross-flow applications, this muffler provides a deep, powerful sound that enthusiasts demand while maintaining excellent flow characteristics.

Key Features:

  • Original two-chamber design for proven performance and durability
  • Cross-flow configuration for versatile installation options
  • Aggressive exterior exhaust tone with noticeable interior resonance
  • Straight-through design promotes excellent exhaust flow
  • Constructed from aluminized steel for corrosion resistance
  • Ideal for muscle cars, trucks, and performance vehicles

The 80 Series offers a louder, more aggressive sound level compared to Flowmaster's milder series, making it perfect for drivers who want their vehicle to be heard. The two-chamber design uses Flowmaster's patented Delta Flow technology to control sound while minimizing backpressure for performance gains.
