The aFe Atlas 3in Steel Downpipe is a direct fit for the 2001-2004 Silverado/Sierra HD 6.6L Duramax LB7. The CNC machined heavy duty inlet flange with turbine gasket and V-band outlet flange ensure an OE-style, 360 degree sealing surface.

Key Features

  • Flow and Performance: The ATLAS turbo down-pipe is made from 3" mandrel bent steel tubing offering smoother transition bends for low turbulence to deliver quicker throttle response.
  • Perfect Fit: The ATLAS turbo down-pipe is an upgrade to the OE down-pipe and utilizes the factory mounting locations for true bolt-on performance.
  • Finish: This down pipe is coated with a black finish and wrapped in thermal header tape for better insulation. This reduces EGT's and under hood temperatures.

Fitment

  • 2001-2004 Silverado/Sierra HD 6.6L Duramax LB7
  • Vendor application: GM Diesel Trucks 01-04 V8-6.6L (td) LB7
