You could set $DisplayFunction-> Identity in each of your Plot statements to
suppress the display, and then explicitly specify
$DisplayFunction->DisplayFunction in your 'Show' statement. An economical
trick when many different plots are combined is to use the Block statement
to temporarily assign a value to $DisplayFunction, which will revert to its
default value when the Show is called outside of Block e.g.

f1[x_] = Cos[x]; f2[x_] = Sin[x];

Block[{$DisplayFunction = Identity},
    p1 = Plot[f1[x], {x, 0, 2 Pi}];
    p2 = Plot[f2[x], {x, 0, 2 Pi}]

Show[p1, p2]
