Description

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.

I was hoping for a quieter muffler than my magnaflow. On my 02 Duramax with magnaflow 4" exhaust this muffler was louder than the magnaflow glasspack muffler. No noticable HP change, no better mpg, no drop in egt... only louder. Loud pipes do not save lives, they just annoy everybody else.
