INTRODUCING THE PATENTED AEROTURBINE EXHAUST
Aeroturbine is the world leader in airflow technology. The company spent over three years in Research and Design to develop the new Aeroturbine exhaust technology.

Most vehicles have extreme restrictions on exhaust airflow, which increases exhaust temperatures and decreases engine longevity. The Aeroturbine breakthrough, based on thermodynamics and jet engine technology, literally accelerates the flow of exhaust away from the engine, leading to:

• Reduced Temperatures
• Increased Horsepower
• Increased Torque
• Increased Fuel Economy
• Less Engine Wear & Tear

Note: This muffler is designed for aftermarket exhaust systems or as a direct replacement for center in center out mufflers. Fabrication may be required.
