Look inside all other mufflers and you'll find simple glass packing or welded plates. Look inside Hooker's Aero Chamber and you'll find the most sophisticated muffler available. The raw aluminiumized 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 as much as 23% better and produce more horsepower and torque than the most popular high performance brand.
