When I get into a looping situation, I usually give it two go-arounds to see if I can squeeze off a shot. If the enemy pilot is any good at all, I won't be able to, and I do something else instead.
1) If I'm near a capital ship I will throw my fighter into a loop around that and then break away from my pursuer, and then turn back. Sometimes the guy chasing me has even run into the cap ship, failing to make a manoeuvrer to avoid it.
2) I'll pick out a friendly craft also involved in a dogfight nearby and tail that instead. A lot of the time, the ship chasing me will get involved in that dogfight, and things will get muddled. I can either run off to find another target, or turn around and try to pull in behind the mess I created.
3) I just pull away at an odd angle and juke left and right a lot with the rudders, if I'm in a faster ship.

There's lots of stuff you can do, but the main thing is to just get a stealthy and solid kill in the first place. Going head-on is just plain dumb unless you are in a firepower monster like the B-Wing.
instead, while you're still out of visual range with the approaching enemy fighter, you can rudder off to the side, and many times they won't adjust course or notice you. Then, you can watch them whizz past, after another target, and silently pull in behind them. Just gauge yourself to a reasonable distance to the enemy and let loose with a continuous burst of lasers until he explodes.
