The first thing we must do is cut the pipe in half length wise.

Place the pipe on the floor and unbend it till it lays straight.
Find the seam where it was put together. *see pic*
(yes it would a been better for us if they woulda just left it apart....)
Now we will use this seam to keep our cut straight.
 

ok break out the knives,saws,guns ;)
you can use many different things to cut this pipe - jigsaw,utility knife,table saw.

Now the idea is to try to keep your cut on the seam.
Don't worry too much if you get off a little bit one way or the other.
Just try to stayas straight on the seam with your cut as you can.
Once you get it cut in half ,on one side, turn it over and find the seam on the opposite side.

Now that you have found the seam on the opposite side begin cutting down the seam again.

Now you should have two halves just as the picture shows.
