AT4040XL Aeroturbine 4" Resonated Muffler


Part # AT4040XL


For those unfamiliar with the Aero line of mufflers, they are a compact stainless steel muffler designed to be added to nearly any exhaust system that offers unrestricted airflow, while having unremarkable sound characteristics.  The XL line of the Aero Turbines is considered their resonated version designed specifically to cancel out any in-cab drone that is typical of many aftermarket mufflers.  

4" ID Inlet
4" ID Outlet
6" Body Diameter
16" Body Length
26" Overall Length

Built from T304 stainless steel inside and out, this muffler does not have any of the traditional packing found in many other mufflers that is known to breakdown over time, but rather uses a series of louvered baffles that are also designed to literally "suck" the exhaust away from the engine, even faster than a straight pipe, which results in lower exhaust gas temperatures. 


64009 - Exhaust Gas Temperature Gauge Kit


Exhaust Gas Temperature (EGT) is a very important gauge to have on any diesel engine, especially if modifications have been made to increase horsepower and torque. The Banks Power EGT Gauge Kit will accurately measure your exhaust gas temperatures up to 1500 Degrees Fahrenheit. This kit utilizes high quality components that are specific for use on motorhomes.

We recommend installing the Thermocouple Probe in the exhaust manifold pre-turbo. This location will provide the most accurate readings.


  • Monitors exhaust gas temperature (EGT)
  • Protects durability by eliminating safe-EGT-level guesswork
  • Eliminates erroneous readings with ambient temperature compensation
  • Accurate within 15 degree F at maximum operating temperatures
  • 2000 degree F-rated, chromel-alumel thermocouple wire provides superior conductivity
  • 1-Year Limited Warranty
  • Illuminated 0-1500F full-sweep face
  • Comes with probe & 55' lead wire
