Here's a video of these guys working on the Focus RS. Seems like they already have a blow-off on it, and the COBB Access Port. They've now installed the internal wastegate actuator to make some more power out of it. Full installation video which is kind of cool.

These guys have been doing some pretty cool work on the RS. Can't wait to see how far they go with it.

Looks so much easier on an STi than the RS but great installation video and you get more boost!

Lol everything is much easier on the STI. But just because they're much more common, it was like the engineers knew it when they were developing each generation lol
