Carefully look at photos P5140005 & P6130094. There are two 3/32" diameter holes visible on the upper inside of the two curved parts of the mount. They are drilled so that their OD's break through the inner bracket's wall. Two 3/32" pins, which are silver soldered to the ends of the adjustable stainless steel hose clamp, are pressed into each hole. You would be surprised at how much force can be exerted on the 3/32" X 1/2" long pins without breaking the silver solder joint. Notice the hard rubber gasket between the hose clamp & tuned pipe.
