Depends on one's reasons I think Jon. I bind my Ulster rep's tailpipe in the vicinity of the passenger 'door' to protect said passengers from 1st degree burns. I don't let my passengers poke about under my bonnet. Binding the manifold may help to prevent fuel vaporisation by keeping down heat transfer to the engine bay? I'm not sure. I had the same experience as Greig in that when I unbound my tailpipe I found it rotten underneath the (asbestos) binding, still lasted 30-odd years mind.
