The Aero Turbine Series 4040 is a 4" i.d. inlet, 4" i.d. outlet Diesel Exhaust Muffler. The 4040 was designed for high-output engines, including diesel trucks and gas engines with 4 inch piping. It is the original Aero Exhaust design. The 4040 was first designed for the racecar circuit. It was proven on both the 600hp Monte Carlos of NASCAR, and the 800hp Sprint car races in Arizona. With feedback from the race circuit being as strong as it was, the 4040 was then manufactured for introduction to the general public as the Aero Performance Exhaust´s Aero Turbine Series Performance Diesel muffler. As the only muffler to have the patented airfoil technology, the 4040 is the hottest new product on the performance Diesel market.

By design, the 4040 is versatile enough to be applied to every American made passenger diesel truck, regardless of the make, model, or year. The 4040 has been successfully applied and tested on nearly every year, make and model of Diesel truck on the market including the Ford Power Stroke, Chevy and GMC Duramax, and Dodge Cummins. 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. The length of the 4040 muffler allows for dual inline mufflers to be placed on the Diesel vehicles as well. Dual inline Aero Exhausts will actually increase airflow and performance, while dropping the Exhaust Gas Temperature even further than a single muffler system, which is directly contradictory to the performance you will see from any other competing muffler product. This is truly a testament to the maximum performance enhancements that the Aero Exhaust muffler creates. The 4040 will give the performance and sound that every performance enthusiast should expect from their vehicle.

The Aero Turbine Series 4040 Diesel Muffler is made completely of stainless steel inside and out. There is no packing or moisture collecting material in the muffler. The hand-polished stainless steel 4040 will give you the look and feel that you want and the performance you deserve. The Aero Performance Exhaust Lifetime Warranty will guarantee that your investment is still performing as long as you own your vehicle.
