Aero Exhaust - TurbineXL AT4040XL Performance Muffler 4" Inside Diameter Necks (Moderate Sound)
The Aero Turbine 4040XL performance diesel muffler is the result of years of design and engineering. It has been proven to lower exhaust gas temperatures while increasing horsepower and torque. Many customers have told us that they have seen drastic increases in fuel mileage by installing the 4040XL on their diesel trucks. The 4040XL is built with a non restrictive internal resonator that reduces rasp and drone. This resonated model will give you a more moderate exhaust tone with the same increases as the standard 4040.
The Aero Turbine XL muffler allows your engine to breathe easier and dramatically increases your vehicle’s performance. When the incoming exhaust gas enter the Aero Turbine XL 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 XL 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. The hand-polished 304 stainless steel will give you the look and feel that you want and the performance you deserve.

Installed on 2017 Nissan Titan XD Diesel 4" system. Excellent finish and easy to install. Added exhaust clamps to my order. Much quieter than expected. Deep exhaust tone but not loud and no drone at highway speeds. Good tone when wide open throttle but still not very loud.
Quick delivery no issues.
Recommend this muffler if you are looking for less noise than straight pipes and easy on the ears.

Installed this on a 1997 single cab long box 7.3 Powerstroke and love it. For the last 4 years of owning this pickup it’s been straight piped and I was getting tired of it and want a nice quiet ride so I bought a 4” straight pipe kit and installed this muffler and it’s awesome. Still sounds great when you get on it but doesn’t have any drone at all on the highway. Took a couple days to break in the muffler but now it’s gotten the aggressive tone and it’s increased my boost 5lbs! Definitely worth the money
