Tune after Cutouts installed???

Hey guys,
Doing some reaserch on getting exhaust cutouts. Ive now been told a custom tune is a must after and also that you wouldent need tune for them.

What do you guys think? Any experience? Any technical explanations(i.e. either AFR doesnt change)?

Thanks for any help.
