aFe Power ATLAS 3" Steel Downpipe, 2004.5-2010 LLY/LBZ/LMM

Fits: 2004.5 thru 2010 Chevy Silverado/GMC Sierra 2500HD/3500HD LLY/LBZ/LMM Duramax Diesel

The aFe ATLAS turbo down-pipe is engineered to outflow and outperform the restrictive, OE down-pipe on your 2004.5-2010 Chevy Silverado or GMC Sierra 2500HD/3500HD with the Duramax V8 6.6L turbo diesel. The 3" mandrel-bent steel tubing offers smoother transition bends for increased airflow, delivering quicker turbo spool times. CNC machined V-band inlets and outlets ensure an OE-style, 360 degree sealing surface. Coated with a black finish, the ATLAS turbo down-pipe is wrapped with thermal header tape to reduce EGT's even in the most extreme environments.
