I was missing one for my F7 exhaust. I took a measurement between the two attachment points and went to the local hardware store and picked up one. I think that headpipe used a 3.25" long "pull" spring. Cost me about $.35 and about 20 minutes of time.

i use any spring i can find to stretch between the hangers! the tighter the better!
