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.

Awesome Muffler, 2003 Cummins

Location: Tucson, AZ
Installed on my 03 Cummins. I had the Silverline muffler previously. I wanted less drone in the cab at highway speeds and towing. This muffler is it! it gave my Cummins a totally different sound in a good way. It has a melow rumble but when you put your foot into it, it comes alive. I am really happy with this muffler. Excellent choice if you are looking for a quiet cab ride combined with a great sound.
I love it, 2011 Duramax

At first I had the MBRP 30 inch quiet tone 4" muffler, I thought it sounded good. Then I installed this shorter muffler and the sound level decreased a tad but has a very mellow gurgle. More throttle response and more mid torque and increased gas mileage and more power in my Eco-Tune. You will feel every throttle movement. Very mellow and quiet around cruzing speeds. Sounds like FlowMaster 3 or 4 chamber. If you want not so loud and mellow tone........ Buy Now. Thanks
