About this product

Part #: 21721HKR

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.

About Hooker

The Hooker philosophy is simple - make real, useable power by balancing the intake and exhaust pressure waves. This efficiently expelles all the burnt gases while drawing in the maximum fresh charge of fuel and air. The Hooker team will sometimes spend twice as much time developing a header to find better performance. Hooker Headers - Do It Right The 1st Time.
