I set one up on a CNC mill, and took it out to almost 63mm (and then went through the wall).

Forget the mill... just use a rat-tail file. It's much faster, and the Al disappears in no time.

I kept the stock diameter around the plate, and just smoothed it out, and openned the rest up a bit (port-matching the backside to the intake).

It's not 65mm, but it didn't cost a dime, and it doesn't whistle either ;-)
