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.

Installed muffler on my 2016 ram 2500 , nice tight sound and my exhaust brake doesn’t sound so loud anymore... highly recommended muffler!

Excellent - Eliminated the drone , added torque, and sounds better than a straight pipe.
2016 Duramax diesel, highly recommended.

Originally my truck had the banks big monster on the truck, but never took a look to see what I had. I ended up buying a MRBP turbo back w/ muffler delete kit. After about a year of starting the truck up at 3 am and having a newborn, I decided it was time to quiet it down a little. After a bit of research I found the AT 40/40XL and liked the way it was designed so I figured I would try it out. I’m glad I did because it was an excellent choice. The engine still sounds great, is loud but not overboard, and you can still hear in the cab w/o yelling. The open design is also great for the flow of exhaust with no restrictions.
