Wasn’t Vader’s TIE an advanced model equipped with a hyperdrive and shields? It’s also possible many more people than just Vader had one of them on DSII.
EDIT: I read the Wiki, and apparently it was built out of a much sterner material, too! So it makes sense that it would survive the DSII explosion in one piece. I kinda doubt all three wings of the Imperial shuttle would be unscathed.
