Here's what
Screamscape has to say about the ride's ending:
There were rumors of some custom scenes that could be added to the start and end of the attraction to spruce it up, but last I heard most of these may have been cut. One that may still be included however may be some kind of gag with an explosion and flying cars towards the end that could put to use a couple of old props that may be familiar to guests who have visited the Hollywood park may remember that park's first Fast & Furious segment on the tour. For now we'll have to wait and see.
