The CSX cars used a bracket similar to that in Patricks picture above. The bracket was welded to the pipe and is stable in two planes, fore/aft and vertical shear (supporting the weight). It would slide between 2 tabs that were welded to the chassis and a bolt passed through the 3 pieces with a rubber tubular isolator (like a piece of 3/8' fuel line (with bolt through it) inside a metal tube about an inch long that was welded to the bracket on the pipe. It locates the exhaust pipe and dampens the vibrations and lessens the harmonics created by the exhaust impulses. Very effective.
