I bought these awhile ago used on one of the forums, don't remember which. They sat in the box until I finally got around to installing them. Rode a few months enjoying them and one day the wife and I decided to take a ride. That's when I learned I didn't quite clear the swingarm on the right can. Wore a hole in it. Bought a replacement from Dale. Thus, one is newer than the other. I attempted to polish the older one to match and got close. Never need repacking! I also have the DB Killers I bought from Dale and never used that go with. Only reason they are for sale is I got a set a Staintunes. Dale gets $679 each plus shipping for the slip ons and $32 plus shipping for the DB Killers. I'm selling the whole shebang for $600 plus shipping.
