Default changing exhaust

When my '08 FXDC was new, had a 103 kit installed, with new fuel mapping and Vance and Hines Big Shots. With 49,000 miles on it, am considering changing the exhaust to V&H Big Radius 2into1. Would the ecm/fuel mapping have to be re-done?

Have to be done. Should be done, absolutely. Going from one stage 1 a/c to another is one thing, but it's a big deal with exhausts, especially going from 2-2 to 2-1

Look into the Pro Pipe 2-1, it's supposedly a much better performer

Thanks for the advice. One reason for considering the exhaust change is that my heat shields are scratched, and one of the tips fell off somewhere. New heat shields, plus tips are 75% of the cost of new exhaust. That would be a simpler way to go.
