Stage two finishes off the intake system and provides the foundation for the modifications that will carry you throughout your project. Our stage 2 system will work on cars equipped with the factory airbox as well! Incorporated into the stage 2 plumbing are provisions to upgrade to our DV relocation kit and highly popular catch can system. With the stage two pipe installed the most noticeable changes are the ability to hear the turbo quite a bit more over stage 1 and more top end power. Purchased without the catch can or dv relocation this kit comes with everything needed to block off the unused ports. Includes: Stage 2 Pipe Kit Silicone Couplers Clamps CNC Lathed OEM PCV Port CNC Lathed Catch Can Integration Port DV Relocation Port Blockoff for DV Blockoff for Catch Can Port
