If you try to make a turbo header from mild steel tubing, like a "normal"
(naturally aspirated) header, it won't last long. The added heat and
pressure from the turbo isn't nice for mild steel. Javad's, and most turbo
headers, are made from stainless steel which can handle it better. I'd take
a 5-1 cast iron header, know anybody with a foundry? :)
