Downpipes may be alright but headers will likely crack as a result of wrapping any place that has salt(Ocean air/ salt on roads etc). The salt is exposed to metal via water when the water evaporates it leaves the residue which is going to lead to stress corrosion cracking. Just be aware of the problem and periodically check and clean the wrapped part.
