Piping to and from the Cobb intercooler core is mandrel bent 2" and 2.5" tubing finished in wrinkle black powder coat. The "Hot" side utilizes a machined clip that allows for seamless integration with the factory style turbocharger outlet. It starts at 2" and quickly expands to 2.5" before meeting the core inlet. The outlet pipe is 2.5" all of the way to the custom billet throttle body adapter. All of this piping tucks neatly behind the passenger side bumper cover, minimizing the flow path from turbocharger to throttle body.
