The aFe Power ATLAS turbo down-pipe is a high-performance replacement for the restrictive factory component on your GM diesel truck. Engineered with 3-inch mandrel-bent steel tubing, it provides a smooth path for exhaust gases, reducing turbulence and allowing for quicker turbo spool times. To manage the high heat of heavy towing or extreme duty cycles, this down-pipe is finished in black and comes pre-wrapped in high-temperature thermal header tape to lower under-hood temperatures and exhaust gas temperatures (EGTs).

For a reliable, leak-free installation, the ATLAS down-pipe features CNC-machined V-band inlet and outlet flanges that offer a 360-degree sealing surface. This unit is designed as a direct bolt-on upgrade, utilizing factory mounting points for a precise fit without the need for custom fabrication.
