If you export to an integer file format anything above 0dB will

be clipped.
OTOH, if the export includes resampling then the peaks in the

exported file will be higher than those at the output of the

master strip. The difference will be small in most cases, but

in theory it is unbounded. Better keep a dB or so of headroom.
