Description
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.

Great upgrade. Mounted it up front, about 8" inches before the downpipe curves upward. Did this to get the max effect. The entire exhaust system is 4". Downpipe to exhaust tip. No other muffler or resonator. No need. Why drive trucks w/ these engines if you want to suppress sound? LoL. The AeroTurbine actually changes the exhaust note to a more stout sound. Not barky or obnoxious. Strong and yes it can be loud. Again, so what? To me clearly this is how the truck should sound. And as important, if not more. The science behind the product will reap some outstanding benefits. If you have a cummins 5.9, Get it. (Invoice # 216701B)

I installed one of these on my truck. It takes the edge off of the straight pipe raspy drone. It gives the truck a nice deep tone, but it is still pretty loud. This is not a quiet muffler.

Will this muffler also help reduce in cab drone that I get from Having a straight pipe system

Answer
A muffler will help reduce in-cab drone but a general rule of thumb is that the longer the muffler, the better job it does at reducing those harsh tones in the exhaust.
