If the pipe passes reasonably near the lower edge of the firewall or an engine mount tube, you could make a support from a short strip (~ 1/4" thick, 2-3 inches wide, and few inches long) of reinforced silicon rubber baffle material.  Sandwich the ends by through-bolting between metal plates - attach one end to the firewall or an Adel clamp on a mount tube and the other to either a small flange welded to the exhaust tube or use a U shaped exhaust clamp and bolt to one of the threaded ends of the clamp, or fabricate a clamp as in the photo below.  I've seen that method used on older certified planes.

Here's a couple of pics of a Stinson support to give you some ideas:

Thanks John, good ideas!  I'll likely have to bend up a longer piece of exhaust tubing to get close enough to an attach point on the engine mount or other area on the airframe.  Pics when I'm done.   Dave
