The bellows are there to aid in installation so you can flex them to get the joints to mate up properly to seat. The solid y-pipe doesn't allow that. It also will not crack over time, think about it, what is the y-pipe mounted to? The manifolds and the turbo. What are the manifolds mounted to? The heads. What is the turbo mounted to? The pedestal. All of which is solid mounted without any sort of flex points and also being that they are all mounted to the same solid area than they will all move together, therefore the flex in the bellows is only to allow for easier installation.
