Any FZ700/750 or FZR1000 genesis (pre exup) will fit the FZX.
"will fit" means just that; it fits the bike; however some exhausts may not
clear oil drain plug or center stand.
Laser has a full inox 4-2 system for the FZX.

check under "catalogue" and search for FZX700 Fazer or FZX750 Fazer.
These are specifically made for the FZX: inox downpipes and 2 Laser cans.
search for a dealer near you.

If you want to retain the FZX low down torque, choose a 4-2 system.
if you want to optimize top end power, maybe compromising a bit of low end
power, then go for a 4-1

I have a full 4-1 inox race headers from an FZ750 with a supertrapp
shortened megaphone, dynojet stage 3 and individual K&N's running on FZR1000
37mm CV Mikunis carbs. That bike rocks, I tell you. Check it under
