Exhast Wrap Advice....is It Worth It ?

[Guest david_l_perry]

I am looking at re doing the exhaust wrap on my hood as its now a bit tatty and I want to extend it to cover the exposed 4 into 1 section

 

 

using something like this :-

 

 

 

 

For anybody that has done this, what length of wrapping am I likely to need (my exhaust is the same 4 into 1 layout as above)

 

 

Is it actually worth it....does it really reduce the heat that much......??

 

 

Ta very muchly

heat reduction is massive.although your box will get hotter the heat moves down the system

I did mine.I got 50 foot.got loads spare .I reckon 30 would do it

buy some extra steel tyraps though.

I have double wrapped the exhaust manifold

It does make a difference

I've seen/read reports that wrapping like this fatigues the manifold earlier; anyone any experience around this? I'm talking purely of what I've read on t'internet (and I appreciate how dangerous that can be!).

 

Personally, never bothered with wrapping myself, but appreciate it certainly gets warm under there

Massive heat difference but cheap wrap is sh!t !!! I got mine from http://www.thermalvelocity.co.uk really good stuff and easy to work with as rob said plastic cable ties are the trick...

my 2b has been wrapped for 5yrs and the manifold is still in one piece cheap wrap fell off rewrapped in the above and as far as I,m aware that is still on there. The car was to hot under the bonnet without it especially after all the tuning work...

Did you guys just use the wrap or then add the spray as well ??

[Guest david_l_perry]

This is from the Europa spares web site

 

"Use this hi-heat coating to finish off a clean and well-protected exhaust insulating wrap installation. the coating will protect the wrap from abrasion and harmful liquid spills. extra resins and binders toughen the surface and help extend the life of the wrap by protecting it from friction. they also seal the pores to minimize the penetration of harmful liquids"

never used it on my wrap

I think the Internet warning on manifolds cracking is probably on mild steel ones not the stainless we use

ive got the thermal velocity stuff. they do sell it on ebay and it was cheaper when i bought mine.

errmm some of its still there, bit of a casualty of the engine swap saga, wants rewrapping but it is good stuff.

Cool, thanks guys. Probably a good point about the mild steel.
