The best insulation is actually just a metal sheet that sits between the two parts: A heat shield. It just needs to be supported by small pieces that won't conduct much hear by conduction from the muffler to the shield. The challenge would be to support it such that the vibration doesn't break it loose. > I got mine ceramic coated, and will keep the list informed as to how long the > unit remains rust free (well, at least on the outside). Interesting. Is it coated both inside and out? > They also include the gaskets, copper nuts, The "copper" nuts that I have seen are just copper plated steel and really aren't any better than plain steel. I've got some brass nuts which really work well, but pure copper would be too soft to be useful. Note that a magnet will attract the copper plated steel nuts, but not copper or brass nuts. > With this new setup I was able to bend the rear apron back to its original > shape, and when viewing the car from the back you can barely see the exhaust. > Very nice setup! Does the exhaust then exit thru the original clearance area on the left? Yes, I hate the aftermarket exhausts that just don't quite clear the bodywork. Unfortunately, all the other ones seem to have this problem. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
