AH, the ol header tethers. What a SCAM that was. Had to be SFI rated, $250 worth!!! Please!!
A couple $2 muffler hangers and a band clamp and my collectors aren't falling off.
(though I did loose one about 10 yrs ago. Couldn't believe it actually, but it did happen. Both tabs broke and it fell off about half track. Took some finesse to get the tubes opened up to make it fit again to finish the weekend.)
