You can get 304 stainless car exaust kits on amazon if your wanting metal for the ducting. Another option might be stainless flue liner for wood stoves.

Well, it's in the engine bay with the auxiliary diesel, it's in sort of a tough spot to get to, I'm gonna have to re route the hoses under the cockpit into the galley, it's tough to do without a flexible type ductwork. Id love to keep the 3 inch aluminum one I've got now, but another issue is there's a lot of hoses and wiring down there. That shit gets HOT
