aFe Downpipe
Take your 01-04 LB7 GM diesel to the next level with aFe's ATLAS 3" turbo down-pipe. Engineered to optimize airflow and improve throttle response, this down-pipe is constructed from 3" mandrel bent steel tubing for maximum flow.
The larger tube diameter and smooth transition bends allow increased airflow between your OE turbo and exhaust to reduce EGT's for quicker turbo spool times. The CNC machined heavy duty inlet flange with turbine gasket and V-band outlet flange ensure an OE-style, 360 degree sealing surface.
