Product Details

The Flowmaster 42441 40 Series Chambered Muffler delivers an aggressive, deep exhaust tone that's perfect for enthusiasts seeking a powerful sound without sacrificing performance. This chambered design uses Flowmaster's original two-chamber technology to produce a distinctive muscle car tone that's become an icon in the exhaust industry.

Key Features:

  • Aggressive exterior exhaust tone with noticeable interior resonance
  • Two-chamber design for maximum performance and classic Flowmaster sound
  • Constructed from durable 16-gauge aluminized steel with fully welded construction
  • Ideal for street/strip and off-road applications
  • Provides improved exhaust flow over restrictive stock mufflers
  • Direct-fit replacement for easy installation

The 40 Series is Flowmaster's most aggressive chambered muffler, offering a loud, deep tone both inside and outside the vehicle. Built with precision-welded construction and premium materials, this muffler is engineered to withstand extreme temperatures and provide years of reliable performance. Whether you're building a hot rod, muscle car, or performance truck, the 40 Series delivers the unmistakable Flowmaster sound that turns heads.
