The box that my exhaust came in was dated August 2021 and I have bad fitment.When I spoke to the sales team about this, they said the early days of the Ram exhausts were made without a jig. I think it was American Muscle that put out a video of how Borla does their exhausts today and all of them use a jig for exact fitment and placement before any welding is done. I guess it depends on the supplier to if some of us got old inventory that was made before they had the jig for our trucks.
