Michael,
     McMaster has a page of schedule ratings........Schedule "10" stainless
is 0.109" wall thickness in the sizes you need.......They also have a page
describing the different stainless alloys........I have not seen a Schedule "5"
thus far..........

Kelly:
 
Yes I was able to locate  a local distribuitor for the stainless version of the elbows like shown on the SDFI page.
 
 
The 2 inch ID 45 degre ells run about 3/16th thick or more wall, and are quite heavy OD is about 2.5 or more.
 
It is listed as a schedule 40 pipe.
 
I may look in to a schedule 5 pipe. I am not up to speed with plumbing nomenclature but I belive a schedule 5 is thiner than a 40 and closer to our needs.

  Michael,
      If you are handy with a welding torch you might consider building
your exhaust header using the method in the link below......The "Weld
Els" are also available in stainless and could be used for the first part
(hottest) of the manifold and thinner gauge tubes for the remainder......
 
    Mcmaster-Carr has a large selection of sizes an alloys........FWIW
