Aero Exhaust Mufflers AT4040XL Details

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.

  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.

Like all Aero Exhaust Mufflers, the 404XL is manufactured using the highest quality welded 304 hand-polished stainless steel, inside and out.The 4040XL has been successfully applied and tested on nearly every year, make and model of diesel truck on the market today. 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. 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 make sure to measure before buying so you know if modifications will be needed.
