i may use a cline regulator in my installation of the OS 1.60 Gemini Twin in my Super Stearman. the tank is too high.
the engine does not have mufflers, so drilling and tapping the exhaust stacks is my only option, but will drilling, tapping (yes even brazing the nipples on) and mounting the nipples at the elbow of the stacks give me pressure?

We haven't tried that, but you may be able to get enough pressure. It would be better to make chambers for the pipes. That way, you'll get better silencing and also better and more even pressure.
