About a year and a half ago, I made a two layered heat shield to replace the torn-up asbestos one. I included a "lip" on the bottom to aid in pulling air in-between the stainless sheets for reducing the heat transfer between the sheets. I have not had any problems, however, I do need to add a spacer in one location as the stainless sheets tend to contact each other due to lack of support in that area (center/top area of the shield). It also looks pretty good. Sean Howley VIN#2345 > Haven't seen it, but they say they're coming out with a new two layer one > that's even better.
