aFe® 49-04041 - ATLAS™ Aluminized Steel DPF-Back Exhaust System with Single Side Exit

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.
