Heat Wrapping Downpipe and exhaust flames?

[DaNnY_LaD]

My Exhaust heat shield on my beeza Is really loose and it knackerd that much so that it is rattling so much it driving me mad!!!
Can i just remove it?

I have a 3'' Downpipe With de-cat and Milltek System...And at the Moment When driving it really hard am getting Small 1ft flames out of the back Is this Normal?
I don't get it all the time just on the ODD occasion?

Also Am looking in to Heat wraping my Downpipe All the way down to the De-cat?Would this be alright if i do this?

Any Advice Would be great :d

 

[crezz]

whe running a decat it would pop and spit a fair bit.. and i took my heatshield of also.. i know mine is a mk 2.. its the cat itself that gets really hot going through the process of cleaning the fumes, so a decat should be fine without one

 

[DaNnY_LaD]

Ta very much crezz

So i CAN take of my Downpipe heatshield and is it alright to wrap it up in exhaust wrap up just past the de-cat

This is the exhaust wrap ive bought? also could i wrap my ATP manifold or is that Asking for trouble?

I was thinking of wrapping my ATP mani .....?

 

[DaNnY_LaD]

Matt part of me thinks thats would be a bad idea as there prown to cracking anyway so keeping heat in?
Would make it crack ?

as i have a atp manifold and taking it off soon to fit a new gasket...

 

[DaNnY_LaD]

so is it alright to wrap my Downpipe then?

I once asked whether this could be done and I think the general response was they wouldn't do it on a turbo vehicle, only on a normally aspirated. Subsequently I didn't do it.

It's ironic as it make perfect sense to try and reduce under bonnet temps, but with these parts reaching such high temps it does make you wonder if wrapping the heat in will make them prone to earlier failure

 

[DaNnY_LaD]

yeah Cox ive done a fair few searches and some people say its good and some say its bad....

Theres a fair few wifes tail aswell on them..My Dp and system is made from T304 steel if that matters?

I don't intend to wrap my Turbo or manifold just the downpipe only Nothing else..I do drive it everyday and don't drive it had all that often But when i do drive it hard i really do lol

 

[DaNnY_LaD]

So is it ok 2do?

 

[DaNnY_LaD]

anyone?

Shouldnt be a problem unless you have something after the wrap that could melt, problem with stainless is it has a high thermal diffusivity so by adding the wrap your transfrerring heat further along the system.

So in other words, watch your rubbers/gear cables etc...

Ta Phil

So the Old jublie trick on the Exhaust hangers

 

[itfben]

Did u get any further with this. Considering wrapping my exhaust mani on my LCR to help get it to flame (got decat and no silencer)

 

[cuprawill]

I've wrapped my downpipe to avoid heat around the cables etc. But I would advise not wrapping the manifold as you will put too much heat into the manifold and it will probably crack
