Exhaust heat wrap

[G@NDY]

Been looking into getting some for my manifold and downpipe and looking at the price and the small manifold it has to wrap (think the turbo is bigger!!), is it worth it? and i bet its very fiddly to tie off and make it look nice? What does everyone else do, i will be buying a turbo blanket from AET as i think they look reeet smart. But i reackon it will cost with the metal ties around £60 for exhaust wrap and with my diy skill (and judging by the mess i have made out of my christmas pressies) will end up looking like a dogs dinner. :Hammer

What\'s your manifold made of cast, mild or stainless? exhaust wrap is great for keeping engine bay temps down but the down side is all that extra temp is kept in the pipes and can soon destroy your manifold. That\'s what i blame for mine self destructing anyway. You might be better just wrapping the down-pipe and fitting the turbo blanket. As far as wrapping the pipes its easy if you can get to them, watch out for the stainless clips as they will cut your hands to bits and expect a bit of skin irritation from the lagging for a few days. When you\'ve finished i would recommend spraying the lagging with high temp paint to seal it.

Thanks for the reply Kevin matey :Thumbsup! The manifold is stainless steel. The turbo isnt fitted yet, so at the minute the kit is sitting in my spare bedroom, so getting to it to wrap it isnt a problem :yes Not sure still wether to bother, guess you wont really see it, but i think the downpipe would be a good idea, and reackon that it would be easy to wrap. Maybe even i could manage it!!.
 How did you get on with that engine anyway matey, did you get round to stripping it in the end??

you can have problems with cracking due to chemicals leaching out of the lagging when its damp. Most offshore companies specify a vapour barrier under any lagging to prevent this.

The lagging should in theory help reduce thermal stresses, a manifold with a uniform temperature should have little or no thermal stresses. Fair enough raising the temps reduces the strength of the material but I doubt many manifolds fail due to anything other than thermal loadings.

Dont have any blankets yet but most wraps and paint on here.
