Stephen,

Here is some commentary on another forum on the subject.

For myself, I used to work in the aviation industry. On piston aircraft
coatings didn't work well on exhaust systems, which were always
stainless steel. The engines were just run until the exhaust burned them
through and they were then discarded. There are some good applications
for the ceramic coatings. The new window tint is one of them. But in my
mind, ceramic coatings for exhaust systems is questionable at this time.
Yes, the technology is improving all the time, but even as good as it
has gotten, I'm not sure it's quite there yet for exhaust systems. But -
being an old pilot and aircraft mechanic, I tend to lean to the
conservative side. I found out a long time ago that unlike with a car,
you can't pull the ol' puddle hopper over and park on a cloud somewhere
when something goes wrong. Though I haven't used the service, I tend to
agree with Ken Wilford as to what the expected outcome may be.

As much trouble and money as the replacement is likely to be, does this type coating actually extend the life of the system and is it worth it?  If you have experience with this or specific recommendations on which product or vendor to use I'd appreciate it.
