The aFe ATLAS 3" turbo downpipe for 2001–2004 GM diesel trucks with the LB7 6.6L Duramax is mandrel-bent steel designed to improve throttle response and reduce EGTs. It features CNC-machined V-band and inlet flanges with turbine gasket, a black finish, and thermal header tape for insulation. This downpipe replaces the OE unit using factory mounts; it is not CARB-exempt and is restricted for sale in California and related NY uses.
