From the Aero Exhaust Turbine Series comes the AT4040XL Diesel Exhaust Resonated Muffler. The original resonated Aero Exhaust Muffler design, the AT4040XL can be used on both diesel trucks and high-output gas engines with 4" piping. Designed for high-output diesel engines, the AT4040XL incorporates a sound-tempering resonator with the proven technology of Aero’s AT4040 turbine muffler into one unit. The AT4040XL utilizes Aero’s patented Air Foil technology giving your truck an incredible performance increase. Completely stainless steel — inside & out — the 4040XL is still versatile enough to be used with every American made passenger diesel truck — regardless of it’s make, model or year — tested on virtually every Ford PowerStroke, Chevy/GMC Duramax and Dodge Cummins. The AT4040XL is an excellent choice for any truck owner looking for performance & fuel economy increases while maintaining a tempered sound.
The Resonated Turbine Mufflers have a built-in resonator — before Aero’s patented Air Foil Cone — lined with high-temperature ceramic packing, ensuring a tempered exhaust tone with minimal effect on Aero’s famed performance increases. The Aero Turbine is based on jet engine and thermal-dynamic technology. The incoming exhaust airstream is rapidly expanded and split via an airfoil cone with an orifice similar to a jet engine. The outer airstream accelerates as it recombines with the inner airstream. The air then begins to spin, due to the velocity and air transfers. The recombining of the airstream creates a vacuum that both muffles the exhaust sound and increases the exhaust flow. The AT4040XL’s length allows for dual in-line mufflers on diesel trucks as well — actually increasing airflow & performance while reducing EGTs more than a single muffler system. No other muffler can make this claim – a true testament to the dramatic performance enhancements the Aero Exhaust AT4040XL Muffler provides.
NOTE: The 3 1/2" exhaust pipe standard on most diesel trucks can easily be bumped up to 4" or replaced with a full 4" exhaust pipe system. Please measure before buying so you know what modifications may be needed. |
