add an exhaust, some pipes, chips, and ecu tune for race fuel or such and I have no doubt the m5 or m8 will hit 220 mph.

Yes that was one of the first questions I asked my tuner back in September last year - what can the car do with the speed limit removed.
And they confirmed +/- 320 km/h. Now for 790 Euro (ECU tune including top speed limit removal + dyno actual driving test) one can really not complain! Yes M5s and M8s will certainly hit a higher target given they are already monsters when stock.
