yeah this stuff is really good, use it on an HQ race car not on my skyline!! i have HPC coated dump so dont really need it to reduce bonnet temps!!

but if you have stock dump and pod with no CAI then i would definately put in on!!!

Every exhaust/mechanic i've spoken too basically said "sure it will help but sure it will reduce the life of your exhaust, expect to replace it within a year depending on how hot things get".

Whilst its good to keep gases on the inside hot it does need to cool down and it can't do that with the thermo wrap.

For a daily driver I wouldn't bother but for a person after every last kw or frequents trackdays i'd do it.

I dont think wrapping a dump is as detrimental as wrapping headers. Ive had mine wrapped for the last 6 months and they look perfect when I unwrapped em a week ago. No discolouring or anything.

Headers run alot hotter than dump pipes and they are the ones that will suffer more heat fatigue than a dump pipe. Usually a dump pipe runs anywhere from 200-400C cooler than the exhaust manifold, which I definitely dont recommend heat wrapping!!

On the contrary, if your on a track day I would remove it, as the dump would get very hot for a long period of time! A quick boost here and there isnt enough to do any damage IMO.

Hi guys, we have one dump/engine pipe that is 3 years old and has been wrapped all that time. Looks like new underneath. Having used wrap for 15 years I can't think of one exhaust that has had its life shortened.

But I can sure think of plenty of other things in the engine bay that have died because the exhaust wasn't wrapped. Stuff like bonnet paint, underbonnet heat shielding, TPS sensors, air con wiring and hoses, power steering reservoirs, air con compressors, inner guard paint, throttle cables etc etc

Bottom line, I believe the benefits far outway the negatives.

Hope that helps

...not forgetting that thermo wrapping your dump pipe will dramatically reduce its life down to anything around 6-12mths.

i wrapped mine due to the fact i wasnt impressed with the under bonnet temps when i replaced the standard pipe. that was around 3 months ago... so we'll soon see if it affects the life of my dump pipe. ;)

there was a thread a while ago...about coating the pipe with some white primer or something spray and then another coat of thermal spray then coating it with the thermal wrap to stop moisture to get the best of the pipe..these were some type of high temp paints..2 coats if i remember correctly..just get a stainless steel pipe or titanium...

Sydneykid, wouldn't most of the under bonnet heat come from the exhaust manifold and turbo exhaust housing though? Wrapping the dump would help to a certain extent, but I would think that it'd still get pretty hot under there.

Also is this stuff re-usable? How does it attach? I was going to wrap my new dump pipe when I could afford it, but now I'm thinking if I can re-use it, I may as well buy the wrap now and just re-use it when I can afford the dump pipe upgrade.

Run it thru water first as it makes the tape more pliable, so eases fitting it to countoured pipes. You also should use the clear coat, kind of like a scotchguard (buy it from the same place you buy the tape) and then using hose clapms to stop the tape running. Twines of wire tend to cut into the tape and dont so as good a job of locating it.

As for shortening the life of headers... im not sure, if the turbo's weight is adequately supported then the main cause for cracking of the mainfold would be temperature changes.

So with the tape applied to a manifold, sure it would retain more heat, but also cool much slower, meaning that the red hot steel wont be rapidly air cooled (essentially quenched) making it more brittle. The controlled cooling of the manifold with tape would probably help the life of the manifold?

Any thoughts on that reasoning?

mmm all interesting respond.  

do we clamp them with hose clamp like what we use for the cooler piping? (or just super glue them:D )

will they work for intercooler pipes too? eg to expel some of the under bonnet heat?

i wouldnt use them on the intercooler pipes...

you however you can use aluminium insulation wrap that air-condition/refrigeration joints use to wrap pipes to keep cool.

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
