I am looking at a set of NOS Screaming Eagle Slip Ons 64924-99 Slash Up for my 2000 Road King Classic but before I pull the trigger, I was wondering if these could be used on my bike since I have a true dual header pipe system.I swear that I read somewhere that one slip on is more baffled than the other due to the original HD header system not being true dual. I am afraid of buying these and having them ruin the performance of my Road King. Can someone verify this one way or the other?

 

First check the head-pipe dimeter. It may not be the same diameter as the slip on.
