John:
Did you know that the "ceramic coating" that is applied to exhaust pipes-if
applied to the inside tubing also-not only acts as a heat barrier, but is
known to increase scavenging of exhaust gasses.Wes Potter was mentioning HPC
coating for a turbo and heating problem the other day- and our company,
Finishline Coating, does the same process. Just letting everyone know...I'll
shut up now.
Thanks,
Russ Meeks
