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