Exhaust leak fixed today. Can't recall what thread this was discussed it so figured I would post it here. There is a fairly common exhaust leak under the driver's seat where the driver-side catted downpipe makes it's connection to rest of the exhaust. It did not look that it was fully seated / squared up so I loosened the bracked and tried to pull together but it was all the way in. So figured since the catted downpipe is a very expensive part that I did not want to mess with it anymore.
Took to the dealer today. He confirmed that this is fairly common and not just R models. It was a simple fix in that he just pulled the connection in the picture below apart. Coated with a high-temp exhaust sealer and reinstalled. I could smell it "burning" when got home so let it cool and then crawled under and checked it. All good now. Drips a little condensation, but no exhaust flow.
Tech had a tube of high-temp exhaust sealer that he said he has had forever. I looked it up and looks like it has been discontinued. So if going to fix yourself just grap something designed for very high temps since this is just past the cats.
