Ay up duckies! ive got some of the insulation type stuff for th eexhaust i brought it from SC spares, i thought it was selfadesive type of afair but its not how do i make it stay on the exhaust???

You can buy proper fasteners for it, probably from the same place you bought the wrap from. Alternatively you can make your own.

I used galvanised garden wire. Start of the exhaust wrapping at one end, and go over the end a couple of times to trap it. Once at the other end, just wrap a loop of wire round and twist it until its nice and tight...

I always use jubilee clips( sorry on the spelling ) just make sure that you wrap it very tight,i take it you are wrapping the LCB up ? it has to be tight to work right,also if loose you will no get it back on as it runs very close to the rear of the front subframe...

i use some copper wire out of my van

[miniman5]

theres no resin or n e thing like that for it then??

[Big_Adam]

dose exhaust wrap do much. just i want to be putting a new exhaust on my El Gordo in the not too distant futurer so if it helps i'd do it.

fi that make sence.

its a must really if you are running as LCB as all heat from exhust is just underneath the carb and fuel pump...It keeps things that much cooler down the back there,loads safer

it aint gonna be self adhesive or have resin to use on it because t will just melt from the heat of the exhaust.

just wrap it like a bandage and use wire or a jubilee clip

It doesn't get rid of heat, just moves it. I found all it does is heat up the floor pan around the gear lever a hell of a lot, heat up the exhaust mountings to the point that they start melting, boil off the grease in the gear selector housing and handbrake guide on the rear subframe and generally make it uncomfortable inside the car. I took mine off.

When fitted though I did notice it changed the exhaust note and there was the benefit of lower temperatures under the bonnet. I couldn't actually notice any performance enhancement to be honest.

As has been said, the way to fit it is to wrap it very tightly around. Trap the bottom end of the wrap inside itself and use a clip or wire to secure the top. The proper clip looks better, with the plus side that all the extra ones you get in the pack can be used as CV gaiter clips which don't foul the hub upright as cable ties do. Also it will cut your hands less often when you need to put your hands down the back of the engine. To get it really tight, fit it wet. Soak it in a bucket for a morning and then thread it on, as it dries it will shrink onto the manifold and really tighten up.

You've not been here for ages Miniman5, what goes on?

actually it does neither. the heat wrap keeps the heat in the manifold/exhaust to speed up the exit of exhaust gasses. if youre really pedantic then you should wrap up to the first box of the exhaust.

personally, wouldn't bother, makes your exhaust rot as it traps moisture underneath, would only consider it if you're thraping a race car!

[neil_g]

it needs sealing with silcone ideally.

As i said before , its does keeps things a little cooler under the bonnet ie a lot !!!,if your running your mini with an LCB front pipe...I would says "yes" it makes a diffrence and "yes" it does make it safer ,im running a few more horses than most folks and after a good run ive seen lcb cherry red,thats not what you want just underneath your carb and fuel pipe,also you engine is breathing that hot air back in ....Think about it lol !!!....

If your running a standard little 998 or 1275 there should be no need for it...but just keep it in mind when you pop a Lcb on ya mini,all that heat off them has to go somewhere....Id rather be safer .and let me engine suck up a little cooler air lol..

Ive used it on my previous two LCB's (RIP!).

The first one was a maniflow mild steel one. All was well and good for a year, kept things nicely cool, but then it started blowing. Unfortunately it rotted away very quickly.

The second was a maniflow stainless lcb. After a year it cracked where 2 of the pipes meet. I was not best pleased. Once I took it off I saw it was totally deformed! (I have pics if you want to see)

I phoned maniflow and asked them about it. They said, the stainless one couldnt cope with the heat and deformend. Using the wrap for road cars is a bit ott i think now.
Fine for a racer when you can afford to replace lcb's all the time!

wierd ive never had one rot ? are we on about the same exhust wrap (fibreglass roll)....if its snapped check your engine mounts.
