I would say placement is far more important than gate size, avoid the obvious stuff: no 90* angles, don't vent only one manifold runner, if possible vent the gate separately from the turbo exhaust. if not, merge them together farther down the downpipe (at least 18" from the turbo exit) at a gradual angle.
