I have rev. 5 of my intake installed and pictures posted on my site. Every metal pipe in the car is ceramic coated. I will have a rev.6, it will change the silicone intake elbow to a different profile (and color) allowing a less restrictive path to the turbo. If you enlarge the last pic on page five you can see the kink in the elbow. I already have the replacement, just waiting for time to install. Enjoy!
