Yes, there is a 2.5# CO2 bottle mounted inside the car with a 85# regulator attached to the boost control solenoids.

I just kind of went to town really. I had pictures of a few other header designs that I went off of for inspiration. I put the flange on the head and put the collector kind of the general area I wanted it to end up at and then built the first primary. From there I took the parts off and bench built the rest with numerous times taking the header on and off the car for clearance checks.
