Product Details

The Hooker Aero Chamber Muffler delivers performance-oriented exhaust flow with a distinctive sound profile. This universal muffler features a stepped acceleration chamber design that increases exhaust gas velocity and maximizes flow efficiency, making it an ideal choice for custom exhaust systems.

Key Features:

  • Single 2-1/4" offset inlet and single 2-1/4" center outlet configuration
  • 16-gauge raw aluminized steel case measuring 4-3/4"H x 10-1/4"W x 14"L
  • Stainless steel perforated internal plate eliminates internal rust and corrosion
  • Three internal bulkheads provide superior case durability and stability
  • Reinforced inlet and outlet connections for long-lasting performance
  • Aerodynamic lens directs sound pressure waves into acceleration chamber for efficient flow
  • Precision stainless steel robotic weld seams ensure leak-free operation

The stepped acceleration chamber design is engineered to improve exhaust scavenging while the internal baffle system controls sound output. The aluminized steel construction provides excellent corrosion resistance, while the stainless steel internal components ensure longevity even in high-heat environments.
