From the Aero Exhaust Turbine Series comes the AT4040 Diesel Exhaust Muffler. The original Aero Exhaust Muffler design, the AT4040 can be used on both diesel trucks and high-output gas engines with 4" piping. Used on the racecar circuit and proven in both the 600HP Monte Carlos of NASCAR and the 800HP Sprint Car Races in Arizona, the AT4040 utilizes Aero’s patented Air Foil technology. Completely stainless steel — inside & out — Aero Exhaust Turbine Mufflers can use NOS without the risk of burn-out, true to their racing circuit heritage. The 4040 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 AT4040 is an excellent choice for any truck owner looking for performance & fuel economy increases.
Aero muffler’s straight-through design ensures perfect flow through the patented Air Foil Turbine cone and is based on jet engine and thermal-dynamic technology. The incoming exhaust stream 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 alters the exhaust sound and increases the exhaust flow. The AT4040’s length allows for dual in-line mufflers on diesel trucks as well, increasing flow & 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 AT4040 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. |
