The bar in the first picture is the much older handlebar that they use to produce. It got recalled so if you have that handlebar, take it to your specialized dealer so they can get Specialized to switch it out for you. Their newer bar has a much lower stack height.
You can fit any handlebar onto the shiv as long as you have a normal stem. If you are talking about the stem sticking out, the shiv comes with multiple towers to place behind it so that the stem will have an aero fairing behind it.

Thanks a lot for the info.

That is actually a Felt Bayonet bar with Profile Design stem. Check here for details about a recall that may affect the stem you have.
You don't want the bar in your 2nd pic (Shiv TT) it only has two reach positions, 3 for width and can't tilt. Looks fast but won't help you be fast.

You can put pretty much anything on the shiv, if that is your bike you may need to get a fit before you look at changing the bars. A shiv with the bars that high and back is a warning sign.
It could be right if you have a short torso, but worth checking.
