Vetterman provides supports for holding up the back end of the exhaoust pipes. For each side there are two 6" tubes that are flattened at one end. The other end is inserted into a short piece of rubber hose and held there by a pipe clamp. The ends of the tubes are attached alternately to the engine block and an attach point on the end of the exhaust pipe. This adds support of the exhaust pipe directly from the engine which vibrates separately from the fuselage / engine mount.
