mandrel is the tool that they use to bend the tubing. old fashioned factory exhaust used a crimping meathod to bend the exhaust thats why they had ribs on the inside of the bend. Mandrel bent tubing holds the tubing to a uniform shape and keeps it smooth, also since it is a smooth bend it helps HP thats why everyone uses mandrel bent tubing. even the factory uses it now.
