I am getting a free 55 gallon tank that does not have an overflow on it and i was wondering if there was a way to put an overflow onto a tank that is not all ready setup for one.

You can purchase a hang on overflow. The u-tube models work best. Look at a LifeReef.

The U tube model does not work the best. right now any overflows that are built similiar to CPR are the best, although a lil expensive. they are much quieter/efficient than the u-tubes.

I will respectfully and wholeheartedly disagree. CPR's are very unreliable. U tubes by nature of their design won't lose siphon like the ones which need a powerhead to keep them going. I switched from a CPR to a Lifereef and never looked back. SW forums are loaded with threads like this and the u-tube overflos are the favorites. CPR's have a bad rep for failing and flooding. As far as noise, a durso stand pipe will quiet any overflow and my old CPR was like a toilet.

If it's an acrylic tank, just drill it with a high speed drill and the right bit.
I've done it without any problems. Then, just build an overflow for the corner. The trick is ensuring you don't make the "teeth" of the overflow to wide, or too deep - otherwise you'll:
Too wide = pull fish into it
Too Deep = your tank will never be topped off / water won't reach the top...unless you have a powerful pump...
Best,
