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.

Sounds the same
Matt (CA) | May 14th, 2022
Put this on my 2016 Duramax 3500 and it sounds no different than before. After reading all the great reviews I figured I would give it a shot. I have not felt any difference in power and have yet to tow my toys with it installed. 3 stars because it looks good.
