Wrapping Headers

[FunE4MG@aol.com]

Has anyone heard pros and/or cons rergarding this "Miracle" fabric that
insulates header pipes.  I've seen it in 1 application and it hasn't been on
long enough to evaluate it yet, but.... The manufacturer claims it helps
develop horsepower by keeping the heat in the pipes thereby allowing better
scavenging.  On the other hand Some parts guy told me that the wrap also
holds water and condensation next to the pipes when it cools off.  Any
insight?
