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.
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.
