Some folks have tapped or glued an elbow fitting into the weep hole and attached a tube to run down past the opti.

There are probably some good threads with pictures, but meanwhile here's an article:

About the only oddball tool you will need is an inverted Torx E4 bit to remove the opti cap. If you get an MSD opti, it comes with a little makeshift tool for this purpose.
Nice work. Where can I get those headers ?
