I had slip-on sidepipes on my early Backdraft build that also proved difficult to remove. I attached one end of hand-crank come-alongs to the sidepipe near the 90-degree bend and the other end to a fixed stud in my garage. I delicately tightened the come-alongs while tapping the side-pipe with a rubber hammer. The side-pipe came right off. Phil
