At a club I belong to we have a 6” uninsulated stainless stove pipe extending well above the roof line of the work shop.
We replaced a burned out barrel stove with an old, solid Gold Marc stove with an 8” outlet. With opening the two doors to load it smokes badly. Obviously, this is a less than ideal situation with an oversized stove and an inadequate sized flue.

My question is this….
Is there any chance that instead of reducing the stovepipe directly from stove and instead installing a couple lengths of 8” and then reducing would improve draft ?

I guess the alternative would be an 8” flue or different wood stove.

Thanks for any input.
 
Yes, the flue outlet shouldn't be choked down, especially with the big opening for the two doors. The options are as suggested.

Is the flue straight up or are there any turns in it?
 
Only open 1 door. Maybe the smaller opening will fool the stove into thinking the chimney is appropriately sized.

Your outside temps are probably hurting draft too.
 
There are two 90’s that I could replace with 45’s if there might be a positive result.
That could help. A picture of the stove pipe indoors and the chimney will help spot areas for improvement. Does the chimney go up through the roof or is it an exterior chimney connected thru the wall in a thimble to the stovepipe?
 
Save yourself the hassle, sell the stove and use the money to buy a stove with a 6" outlet. Almost every stove is that nowadays. There are used stoves on craigslist and marketplace and other online places.
