Aero Exhaust AT4040XL 4.0″ Muffler – Moderate Sound Performance

The Aero Turbine 4040XL performance diesel muffler is the result of years of design and engineering. It has been proven to lower exhaust gas temperatures while increasing horsepower and torque. Many customers have told us that they have seen drastic increases in fuel mileage by installing the 4040XL on their diesel trucks. The 4040XL is built with a non restrictive internal resonator that reduces rasp and drone. This resonated model will give you a more moderate exhaust tone with the same increases as the standard 4040.

The Aero Turbine XL muffler allows your engine to breathe easier and dramatically increases your vehicle’s performance. When the incoming exhaust gas enter the Aero Turbine XL muffler it is rapidly expanded and split via our patented airfoil cone technology with an orifice similar to a jet engine. The air begins to spin because of the increased velocity and pressure transfer. The outer air stream then accelerates as is recombines with the inner air stream. The recombining of the air streams creates a vacuum that both muffles the exhaust sound and increases the exhaust flow. Thus allowing your engine to breathe easier and dramatically increasing your vehicle’s performance.

The Aero Turbine XL allows for more efficient combustion to create added power, rather than simply dumping more fuel into the engine. This muffler achieves incredible performance and improved gas mileage all while creating one of the smoothest, throaty sounds on the market. The hand-polished 304 stainless steel will give you the look and feel that you want and the performance you deserve.
