not tried the ceramic coatings
but they do look bloody good, think they have to be applied to the inside of the pipes to retain the heat etc, in which case it's done to new pipes only(i think??)
i wrapped mine, takes virtually all the heat out. the frame and shock are now just warm after a good ride. they were untouchable before
it has got pretty dirty over the months, so maybe i would try black wrap next
kev
Also Arent you supposed to soak the wrapping in water first to expand a little then when it dries out it is super tight to the exhaust and seals correctly ?
