Daniel,
I seriously doubt you would need to make another exhaust manifold for your

Hey Paddy, what materials did you use to make that exhaust manifold? I want
to make one for my z18et but just wondering what others use in such a
situation? Beautiful job on the whole setup to, I just love that chromed
intake plenum!!!!!!
