Aero Exhaust Aero-Turbine Resonated Performance Muffler AT4040XL- Universal *

<p>Description Aero Exhaust Aero-Turbine Resonated Performance Muffler AT4040XL- Universal * * UNIVERSAL - 4" INLET/OUTLET X 26" LENGTH The Aero Exhaust AT4040XL Aero-Turbine Resonated Performance Muffler gives your truck an aggressive, yet more mild tone due to the resonated design. Built for high-output diesel engines, the Aero-Turbine Performance Mufflers feature a patented airfoil technology that increases horsepower, torque, flow and also reduces temperatures. The AT4040XL is the only performance muffler that will give you the performance of a full system at a fraction of the cost. Most vehicles have extreme restrictions on exhaust airflow, which increases exhaust temperatures and decreases engine longevity. 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. Featuring a T304 stainless steel construction, this resonator has a high-temperature ceramic packing material to help absorb sound waves.
