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 aerodynamically designed chambers flow 23% better and produce more horsepower and torque than the most popular high performance brand.
