Product Information

Product Details
Part No. 21505HKR
Warranty Details (90 DAY REPLACEMENT IF DEFECTIVE)
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.

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