I personally believe they are referring to anything AFTER the primary tubes, ie. extensions , collectors etc ...Instead of just shoving the collector on to the extensions they really are not or nothing is fastened to the primary pipes--they want to make sure that the tubing from the header flange to the tip of the collector is one piece such that at no time can any portion of the tube(s) comes apart unless/until it is unbolted from the previous part.--Makes sense to me--- FED387
