Hi,
        Why not make a custom plenum from aluminium?. It's cheap, can be
polished, is easy to modify later and it works very successfully when bolted
to most metals. Just buy a sheet of 3mm aluminium from a scap metal joint,
fold\scuplture it your desired application and MIG or Tig the joints
together. Seen some on twin turbo motors with wild looking plenums. hope
this helps.
