I request an sound update for the 125 models?

can you change the sound of the 2 strokes? i think it's up for an update

I was thinking isn't there an possible way to change the sound of the bikes. Not that i don't like it but it would be sick as whe can change aspecially the 2 stroke. 4 stroke sound ain't that bad but the 2 stroke sound could be better.
I apologize for my bad english im from the netherlands.
