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 include three internal bulk heads for superior case durability and stability, a stepped acceleration chamber, a resonance chamber and tuning tube to cancel unwanted frequencies, and a sound absorption chamber. It also includes a stainless steel perforated internal plate and reinforced inlets and outlets.
