Aero Exhaust - Turbine AT4040 Performance Muffler 4" Inside Diameter Necks (Aggressive Sound)

The Aero Turbine 4040 is a 4.0" inlet, 4.0" outlet performance muffler designed for high-output Diesel engines. The 4040 is currently being used on a wide variety of gas and diesel applications. As the only muffler to have the patented airfoil technology, when you install the 4040 you will not only get the benefit of increased exhaust flow but you will also receive a deeper, more aggressive exhaust sound.

The Aero Turbine muffler allows your engine to breathe easier and dramatically increases your vehicle’s performance. When the incoming exhaust gas enter the Aero Turbine 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 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. There is no packing or moisture collecting material in the muffler. The hand-polished 304 stainless steel will give you the look and feel that you want and the performance you deserve.
