Over 90% of the header problems we see at Softys (blown gaskets, bolts coming loose, pipes cracking, etc.) are caused by the movement of your exhaust system & engine. Your engine torques moving up & down around its rotation. Your exhaust system moves side to side cornering & up and down on bumps. What's in the middle - your headers. The simple solution is to put a flex joint in you system just behind the collectors & here they are.
