Spencer, I'm tighter than a duck's bottom under-water (ex Yorkshire and now living in New Zealand) but whilst the methods outlined by the previous posters will undoubtedly work (particularly I understand the sand bending) there is quite a bit of time to be invested in the setup, former etc...
It may well be worth scouring your local area for a tube bending firm who does jobbing work or short productions runs. A muffler shop is unlikely to give you the absence of necking that you require.
I've had some small items bent locally before and if you are prepared to wait for them to have a run of your diameter of tubing (and thus the setup) it may not be that expensive. You may be lucky enough to have somebody locally with a CNC bender.
Worth looking around before you commit to DIY and several attempts to get it bang on.
