Wicked heada guy

Vacuum hose makes great headers. Well, for mockup.
I first started with an equal length design, then abandoned ship when i saw how many bends there would be. Apparently equal length isnt that big of a gain in turbo applications. Dont try to convince me otherwise because ive decided to take the easy way out.


Equal length:




Not so equal length:
If I were to start over, i would make the collector first. I made a cardboard mockup collector which i later abandoned(after starting the header) because it was ugly, even in cardboard. Now my collector design has completely changed due to an almighty vision, and i may have to modify the current pipe configuration to make it work. Oops. I know the outlets look like theyre never going to join, but its in the eye of the fabricator(me).

Much prettier collector design(notice im not even showing the cardboard design). For this, i cut two sections of 3ish inch pipe, then cut them lengthwise. Then welded a halfinchish piece to the top of each. Its gonna take a lot of work to get them to blend together, but the ladies will just love it. Or not.
