exahust port size

[bnaellis]

The one on the left was my exhaust port compared to another exhaust port that would be considered large. My exhaust port was actually quite a bit bigger than in that picture but I had not yet finished at the time. Maybe give you an idea of what kind of size you can go and still have the inserts.
