I don't guarantee the coating won't flake off and get ingested into your engine when you start it, though... there's a vacuum when you start the engine... which is why flaky cats have killed QR25 engines in the US... but it should do the same job that header wrap does.
+1 on Niky's DIY suggestion.. :thumbup:
