Kevin: We did exactly that with our 1500 Midget. Buy a weld-on flange (we
got ours from
the machine shop we deal with )in the proper pipe size and have one portion
welded to
the header. Give some careful consideration to where it will be on the car
to facilitate
installation and removal of the bolts. Likewise consider orientation of the
bolt holes. On
our header, all the pipes came together before a vertical run (4-1) so we
put
the flange in the vertical portion of the downpipe to make for better ground
clearance.
With one portion welded to the header, install the header, bolt on the
mating
part of the flange, and install the remainder of the system, aligning it
with
the flange bolted to the header assy. Then, weld the last connection with
it on the car. Otherwise, it is difficult to ensure alignment of the
flanges.
