I feel for you big guy. I live in fear of needing a new exhaust...to the point that I may have mine taken off in the spring so that I can draw a replacement one up so I can have one built.
I really like how neat the factory one on my GTC fits, and like a single outlet as well. I have looked at literally hundreds of systems through the years, and have never seen one like the Puma system.
It's just one of the little things when you own a limited run auto.
I have to develop a heat shield for mine to keep the paint on the body behind the license plate. Still, the car is really getting refined. No rattles to speak of.
If I could only finish my windows and door panels...
