The FSE power boost valve listed for the probe will fit.
Induction Kit - Probably will fit but a CAI wont. The reason is the inlet manifold on the xedos is the same as the KLZE engine which noone seems to do a cai for. You can always get a universal filter cone which will fit. Probably cheaper.
Exhaust - Well with the 6 there isnt many options. Custom S/S from somewhere like powerflow or a Scorpion Back box. Not sure on your exhaust configuration (will check in a min) but i guess its different. So get a custom S/S its less than you think. Get it decatted if you are looking for power.
I've just checked a pic I took of my old Xedos engine bay and compared it to the MX6 and the VAF and airbox is indeed slightly further forward. Still, one like the Zenxsport may fit, we'll have to measure up one day:
