Paul,

Which header flange do I use RB or Maxdatrix?  Assume the stainless
flange? what size tubing OD ID? Thanks for any help

I think Mazdatrix sells the RB header. I don't think it
is stainless.  I think it is mild steel. If you want to cut some weight
this is the way Everette Hatch did it.

I would use two inch if you can squeeze it in. Otherwise 1.75" dia. does

not

seem to hurt that much.

Paul,
I found a stainless flange at Mazdatrix PN 16187 and asked them via Email
what the ID was for the pipe holes. Reading their Email response dosn't seem
too promising to get an answer.

I'll see what I can find out about it on Monday.
