Just have to google my friend
( don't google "my friend" it won't come up with anything interesting... )
Wrapping a downpipe is a bit tedious.. the best way to do it is ceramic coat a few layers... then wrap with exhaust wrap tightly with high heat steel ties... then coat it with RallySportDirect.com - DEI Design Engineering HT Silicone Coating
That silicone coating will help prevent moisture... it'll still get in there, but moisture is getting inside your heat shield as we speak.. it's not a sealed system... exhaust rusts. It's a fact of life. When I took my stock exhaust off at 15k miles.. it had rust on it.
