Should I get Headers ?

I have a 2023 S1000RR.

I’m thinking of getting headers , but retaining the stock end pipe which is Akrapovic (bike came with this from factory).

Any recommendations ?

My intention to have this is purely for the sound, nothing more (it is just a “want” and not a “need”)

I don’t want it too loud though.

My main concern is >

1: Will it affect factory warranty ?

2: Do I have to change the ECU mapping (I prefer not to) ?

Please advice.
