No - ZX10R pipes won't fit a ZRX. Not without huge mods. The ZX10R pipes have a much steeper angle of exit from the head, compared to ZRX pipes which exit the head only a bit below horizontal.
ZX10 pipes from the early model - at least the header pipes - could well fit straight onto a ZRX without any mods. Same with header pipes from any ZZR1100/1200. The motor is basically the same. The rest of the exhaust system might need some work though
