I have seen situations were a piece of larger diameter stainless tubing in either a strait or curved run is cut through the center lengthwise using either a Bandsaw or Plasma cutter so you essentially have a half tube in any plane. For instance if the exhaust tubing is 1.750 diameter, you use 2.250 (or larger)and split it. Then fabricate and weld on discrete legs that make it stand off the smaller tube by .250" or more depending on 1/2 the difference of the tube diameters. Then use narrow stainless hose clamps to secure it to the smaller tube. What you end up with is an air gap and a small heat shield. Is very effective, can be made to follow the tubung run exactly, and used in a limited area instead of matting if you are attempting to protect a specific component in a confined area. Done right this can be made to look very goodand well thought out.
