Another alternative
Here's another one for you... Almost all motor homes I have had the pleasure of working under have had exhaust you can readily replace with parts from any truck dealership parts department. There are normally just several parts that the factory may or may not weld together. You will have a flange at the turbo witch just corresponds to the turbo flange size/style, then a few elbows of specific angles to the chassis, some flex of the appropriate size/length, a muffler dictated by available space and another elbow coming out. Even the hangers can be located In a "truck exhaust" catalog. You will be shocked at what the coach mfg will want versus the truck shop. Even NAPA has catalogs. It's not that expensive at all. Just takes some time and flexibility! There are aftermarket mufflers available as well that may give a slight mpg boost or at least make it sound faster. Search for aero turbine muffler/resonator as an example. It is a little labor intensive so get some estimates first.
Enjoy,
Allen
