Screaming Eagle Slip Ons Question

[cubalz]

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?

mufflers will be fine , both are the same , make sure you check the header pipe size
some duels pipes are larger then others
