Product Details

The Flowmaster Super 44 Series Chambered Muffler delivers an aggressive, deep tone for enthusiasts seeking maximum sound performance. Built with race-proven Delta Flow technology, this muffler provides exceptional exhaust flow while producing Flowmaster's signature aggressive exhaust note.

Key Features:

  • Stainless steel construction for durability and corrosion resistance
  • Delta Flow technology with chambered design for aggressive sound
  • Designed for street/strip performance applications
  • Moderate interior resonance with maximum exterior sound
  • Direct-fit replacement for original equipment mufflers

The Super 44 is Flowmaster's most aggressive sounding muffler, ideal for muscle cars, hot rods, and performance trucks where maximum sound output is desired. The chambered design eliminates internal packing materials that can degrade over time, ensuring long-lasting performance and sound quality.
