At first I agreed, but then I think maybe it isn't actually all that silly. What if you want to hear your engine make happy sounds, but you want less of other less welcome sounds, like road noise, DI injector noise, etc. Putting in a sound tube allows GM to engineer the car to be quieter overall but without muffling the part that makes you smile.
