| Wow. if only you had told me not to do that! btw What heat muff? ;-)
a point I forgot to make is that aircraft exhaust is very thin metal compared to auto, which is why jet hot isn't more careful...
Skip - have you inspected your turbine wheels to find the alleged damage from ceramic flaking off and hitting the blades?

I sent my exhaust to Jet Hot (which is primarily for cars) and when I got it back, some joints were a little loose but others wouldn't fit at all. I don't know how they did it, but some of the joints were visibly out of round. I had to take them to another shop to try to get them bent back into shape, which resulted in slightly leaky joints. Eventually, I had to have a new exhaust made. I took the new pipes to Olympic Coatings in Escondido and had their gray high temp coating put on. Several years and a few hundred hours later, it's still going strong. I had both the inside and outside of the pipes done, however it's important to remember NOT to coat the pipe running through the heat muff. Doing so will greatly reduce the heat transfer.
