Here's the finished product. Notice the gap at the end. When mounted, there is a 1/2-inch gap between the two. There are several reasons for this. One, the gap won't transfer the heat of the exhaust tube to the bedside. Two, I'm going to wrap the gap in exhaust wrap, which will dampen vibration and keep the exhaust from tearing up the bedside. The exhaust wrap will also seal the gap and reduce heat. As added protection I created a gasket from the wrap to mount between the tip flange and the outer bedside.
