As some of you will know I'm just 1 week away from rebuilding my engine. One of the things being bolted on will be an XS exhaust manifold. Now, there's been a few issues with these manis already with them melting silicone hoses and cracking. I've hopefully sorted out the crack risk by getting the welds beefed up (thanks s3dave) but i'm now looking into wrapping the thing like in the following link:Heat wrapping exhaust - uk-mkivs
Has anyone got any experience with this and different types of wrap? Will it be ok on our super hot cars and is it worth doing this rather then fabricating a make shift heatshield to put between the mani and any hoses.
Any thoughts or advice would be good.
