AFE 49-04093 Atlas 3" Turbo Downpipe

Made from 3" mandrel bent steel tubing, the AFE 49-04093 Atlas 3" Turbo Downpipe is a superior upgrade for your GM 6.6L Duramax LB7. 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.  Coated with a black finish, the ATLAS turbo down-pipe is wrapped with thermal header tape to reduce EGT's for improved performance and durability.

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.

The ATLAS turbo down-pipe is an upgrade to the OE down-pipe and utilizes the factory mounting locations for true bolt-on performance. 

CNC machined, heavy duty inlet flange and quality V-band flange are used for a complete 360 degree sealing surface at the turbo housing and exhaust system. 

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.
