On the F-14 as you can see from a picture there is some exhaust like thing in between engines. What is this?

This is the line for dumping fuel in an emergency. If the F-14 needs to land quickly but is too heavy for landing, fuel can be pumped overboard through this pipe. To the left of it is an antenna, and the rod below the fuselage is the arrestor hook.
The Australian F-111s use the same arrangement to great effect during flight displays.
From the F-14 Walk-Around Photo Index Page:
Back end of the "beaver tail". The red hole is the fuel dump point. The beige item is the rear ALQ-126 antenna, paired to the ones on the wing glove area. This antenna, like the forward ones, was introduced with block 110 F-14As and all subsequent aircraft. Also visible is the hook portion of the arresting hook.
1$\begingroup$ Cool. From its appearance and location I would have guessed it was an APU exhaust. Do fighters even have an APU? $\endgroup$– TomMcWSep 29, 2015 at 22:48
1$\begingroup$ @TomMcW: Yes, most modern ones do. See here for a related question $\endgroup$ Sep 29, 2015 at 22:54
The only thing I can add here, is that the two square holes on the underside next to the tail hook, are for the chaff and flares.

That said, I think it does add interesting information so I think we can have an exception here. Just remember, next time use the comment feature to comment (-: $\endgroup$– kevinJul 27, 2018 at 8:14
$\begingroup$ From the picture holes look right above the hook. I wonder how they avoid hitting the hook. $\endgroup$– KolomFeb 1, 2021 at 15:26
