Hey, are the runner pipes for the intake manifold the same diameter as the throttel body (65.5mm) on the GT-S?

The only other things I can really think of are extrude honing it to smooth out the interior and maybe adding velocity stacks to the entrance of the runners, but that would probably be a PITA.
It already has velocity stacks cast in - I cut one open to look
