The ATLAS Exhaust System channels the exhaust from the engine to the rear of the vehicle on a racing diesel engine truck. It has the least amount of exhaust flow restriction possible to enable the engine to make more horsepower and torque and operate with reduced exhaust gas temperatures.

Features:

• The least restriction for maximum airflow
• Aggressive Sound
• Improves performance
• Reduces exhaust gas temperature
• Flow bench and dyno tested
• Tubes mandrel-bent
• Aluminized for durability
• Welded hangers with swaged ends
• Slotted and swedged ends
• Premium quality band clamps
• Backed by a 2-year limited warranty
• Proudly made in the USA

An off-road exhaust system must safely carry harmful exhaust gases to the rear of the vehicle, away from the driver. But it must do so with the least amount of restriction, for maximum airflow and power, under the most demanding conditions. To achieve this, the right pipe size and every bend must be carefully calculated.

aFe tests its systems on the flow bench and the dynamometer to determine the right pipe size and muffler construction. Then they mandrel bend the pipes to ensure they maintain their shape and size throughout the entire length, to provide smooth, unrestricted airflow. Tubes that are not mandrel bent can lose up to 20% of their diameter in sharp bends. A free-flowing 12" wide muffler is included in systems that feature a muffler. Some systems include a straight muffler delete pipe if a more aggressive sound and maximum flow is desired.

But performance is only part of the equation. A quality exhaust system should be easy to install and made to last. The muffler and all pipes of the ATLAS exhaust system are constructed from aluminized steel. To ensure a tight seal, slotted and swedged ends are used whenever possible. When used with the supplied premium quality band clamps, the tightest, leak-free seal is the result. Every hanger is thoroughly welded on each side to ensure a strong attachment and the hangers also feature swaged bayonet ends to lock in place once installed. The factory mounting locations are used throughout and a 2-piece tailpipe facilitates adjustment.

DETAILS:

This ATLAS DPF-Back exhaust system utilizes 4" aluminized tubing and eliminates the factory muffler, significantly improving the sound of the F-150's exhaust system. It's finished off with a large 5" black exhaust tip.

• Constructed from mandrel-bent 4" aluminized steel for maximum airflow
• Utilizes factory mounting locations and requires no cutting or modifications to stock parts, making for a quick and easy installation
