I was definitely underqualified to build mine. So was the $60 used wire welder I bought to do it in my garage vs the shop back home, but we got it done and been leak/crack free for 6yrs now of street use. From years of observing and reading it seemed using OEM manifolds was key to success. 2nd best would have been logs made from sch40 Weld Els, from both a skills to build and durability standpoint.
