The turbo downpipe can be installed with the heat shielding. The pipe will interfere with one upper shock mount on quad-shock trucks, so the pipe must be dimpled to clear. Adjust the shielding to protect the nearby injectors, return hoses, and glow plug wiring. Adjust the positioning of the hoses and wiring to provide maximum heat protection. You will also have to adjust the AC lines carefully to clear the turbo.
