This point should be carefully clarified. A 6" stovepipe has a 6" internal diameter, which should more or less match the hole in the back of the stove. Because you can buy double wall stovepipe, and triple wall chimney pipe, the outside diameters increase proportionally.
It's OK to go from a 6" stove exhaust to an 8" stovepipe, but never, ever in the opposite direction, ie: an 8" exhaust into a 6" stovepipe. That would be an instant violation for which you might get a fine from the fire department, and total nulification of your insurance.
Research it carefully before acting. It is doable however to change out your chimney with a larger one. It's just a one day job. I've already installed two chimney's in my cabin myself. You'll be using triple wall chimney pipe where the flue passes through the roof, and also where-ever the flue passes through a wooden floor. Remember that you'll need 2" of clearance around any triple-wall pipe that passes wood.
