It is possible to create too much draft. But going up just one pipe size
won' t do that. I have a fireplace insert with an 8 inch outlet and my
chimney is 12 inches square. Sometimes when i open the stove doors, it
just goes ape! Also the smaller pipe will stay cleaner due to it's running
hotter.

I'm installing a woodburning stove that accepts 6" stovepipe. Is there
any advantage to using an 8" chimney or can I keep the chimney at 6".

The chimney is not yet built.
