I have tried to determine if I had to remake it how to make the transition from the flat oval to the round of the muffler. If there is some quantity involved to justify the time I could have the folks in the shop use the CAD/CAM and programming to define the shapes and sheet metal sizes and then it is just a matter of TIG welding the exhaust tip together and polishing it. As an alternative its shape can also be a rectangle at the outlet which would greatly simplify the fabrication of the exposed part.
Before the overhang on the 45 foot coaches came to be the 40 foot coaches just used a round pipe, polished where it was exposed and that would work as long as you were aware of steep transitions in the road that would damage the pipe. As an alternative you could go into a 90 degree going forward, then a second 90 just behind your Webasto / Generator exhausts leading into a polished exposed tip which would be far enough forward to minimize damage.
