Will depend partly on whether your local code requires double-wall for the portion going through the garage - many areas allow single-wall or galvanized double-wall (if you accept that) as long as the in-room portion is at leat 12 inches from the walls and ceilings - makes quite a difference in per foot materials cost. I think most areas require stainless double-wall on the portion within the walls up to the roof unless containedwithin an old wood burning or other flameproof chimney. Also - howstraigth the run it makes quite a difference in cost, as does requirements for firestops around the flue whereit passes through floors and roof - whatthe requirements are can up to double your installation cost, plus add cost for repair and painting of drywall holes that have to be made to install the fire collars.

here are a couple of prior responses that should help - more right below the answers -
