OS Max 200 4-stroke thread size


       Remove this ad - become a site supporter!
I have an OS Max 200 4-stroke and I want to make a custom muffler/manifold for it.
I know that the thread in exhaust pipe on the motor is 16mm but I can't find what the thread size is.

Does anyone know what tap is needed to match the thread on a 200 and a 120 4-stroke OS motors?

OS makes a flex pipe for the 120 but not for the 200. The plan is to adapt the 200 onto the 120 flex pipe for this project.
