^^^absolutely.
'Irreversible' shouldn't be any kind of a deciding factor if you're relocating sensors. Once your set of Euro's are in, there's not a chance you'll ever revert back to stock. Not for resale, nothing.
You can run them fine with/without a tune and no CEL.
It's a different story with the Fabspeed headers & their bung location - using a tune (Evolve) to turn down the sensors. It's a more permanent decision because you'll need to keep the tune with the car for things to run properly.
