Product Details

The Flowmaster 40 Series Chambered Muffler delivers an aggressive exhaust tone that enthusiasts have trusted for decades. Engineered with Flowmaster's original two-chamber design, this muffler produces a deep, powerful sound on the exterior while maintaining moderate interior resonance.

Key Features:

  • Aggressive exterior exhaust tone with signature Flowmaster sound
  • Original two-chamber design for maximum performance
  • Constructed from fully welded 16-gauge aluminized steel for long-lasting durability
  • Ideal for street/strip, off-road, and performance applications
  • Moderate interior sound level - noticeable but not overwhelming
  • Straight-through laminar flow technology reduces backpressure

The 40 Series is Flowmaster's most aggressive street muffler, perfect for muscle cars, trucks, and SUVs where maximum sound and performance are desired. The durable aluminized steel construction withstands extreme temperatures and harsh conditions, making it an excellent choice for both daily drivers and weekend warriors.
