I fabbed a turbo manifold out of ASTM A-106 mandrel bends (probably the 
aforementioned weld "L"'s) I used 1-1/4 nominal size, heavy wall.  0.160" 
wall with chamfered ends for welding.  collector was 2" x-heavy at 0.220" 
wall.  Welds nicely, quite clean.  ASTM A-106 is a low alloy steel as far 
as I can tell.  I couldn't afford the stainless, not to mention the 
additional fabrication and welding issues.  THe 1-1/4 nominal size is 
actually closer to 1.4 inches if I remember correctly, and the ID and OD 
vary with the "weight" for the same nominal size.
