Pics of the truck, please.
I remember the other post on this topic and thinking, that's an odd one-off. Apparently, this is not a one-off. This is a quality control fiasco, since the dual pipe exhaust pieces was a fairly new aesthetic feature addition, and IMO, it looks quite good, when properly assembled.
I believe that the dual pipe tip is a weld on assembly, so it is not a super trivial fix. A dealer could perform this corrective work, if they had the proper experience and incentive to do so. If it were me, I'd probably say f**k the dealer, and I'd take it to a local exhaust system shop and have the corrective job done professionally.
