The Aero Exhaust AT4040 Aero-Turbine Performance Muffler provides your truck with a deeper, more aggressive exhaust sound. The AT4040 is the only performance muffler that will give you the performance of a full system without breaking the bank. This Muffler is designed for high-output diesel engines and features a patented airfoil technology that increases horsepower, torque, flow and also reduces temperatures.

Most vehicles have extreme restrictions on exhaust airflow, which increases exhaust temperatures and can affect engine life and performance. The Aero-Turbine breakthrough, based on thermodynamics and jet engine technology, literally accelerates the flow of exhaust away from the engine increasing performance and engine efficiency.
