Would I need to recalibrate a 2009 Harley Davidson Fatboy if I drilled out my baffles?

Wondering if I did this, which would change the exhaust, if I would need to get the bike recalibrated. I'm wanting a little bit more sound out of my bike as the reason for possibly doing it. Is there any chance that doing this could have negative effects on my bike? Thanks
