Overview

The raw aluminized steel Aero Chamber is designed to do much more than simply muffle exhaust noise. The Aero Chamber Muffler produces a deep throaty powerful sound that will not change with time. The Hooker Aero Chamber uses a unique step principal, similar to that which is currently popular in racing header design. The aerodynamically designed chambers flow 23% better and produce more horsepower and torque than the most popular high performance brand.

Features:

  • 4-3/4"H x 10-1/4"W x 14"L 16 Gauge Raw Aluminzed Steel Case
  • Reinforced Inlets and Outlets
  • Single 3-1/2" Center Outlet
  • Feature intricate stainless steel, robotic weld seams
  • Single 3-1/2" Center Inlet
  • Stainless Steel Perforated Internal Plate Eliminates Internal Rust
  • Sound Absorption Chamber eliminates High Frequeny Sound Waves for Deep Throaty Powerful Sound
  • Aerodynamic Lens Directs Sound Pressure Waves into Acceleration Chamber and Out of Muffler
  • Resonance Chamber and Tuning Tube Cancels Unwanted Frequencies and Amplitudes (No annoying tin can sound or drone at cruising speed)
  • Stepped acceleration Chamber Increases Exhaust Gas Velocity and Maximum Flow
  • Three Internal Bulk Heads for Superior Case Durability and Stability
