Exhaust bellows in hot-pipe?

I am trying to build a set of compounds and the HT4B will not fit between the frame and engine. I plan on keeping the heat exchanger in place. The HT3B fit perfectly fine there a few years ago. So now I'm gonna mount the Primary over the fender and I need some ideas on how to brace it. If I brace it to the frame I'm gonna need an exhaust bellow. The manifold is angled down and I plan to have the hot pipe come up over the the secondary.



Any possibilities you guys can pos some pics of your bracing or places to buy good exhaust bellows?
