[Healeys] bending exhaust down pipes

[john spaur]

I need to adjust my pre-shaped exhaust down pipes and I have access 
to a hydraulic pipe bender. I have experimented a little and when I 
bend a pipe it does not seem to go in the direction I would expect it to go.

Are there any trade secrets or tricks to figuring out how to get a 
pipe bent a few degrees in a predictable direction?

Thank you,
