Aim: To wrap ya headers in header wrap


Required:

* 15 metres of 2" wide header wrap for a standard sized 4-2-1 header like mine,more if bigger.I used 'thermal wrap',it's the best stuff.I bought 20m becuse I will wrap my cat soon,cost = $62 from 'QLD diesel spares'.

Note: If your headers have lots of bends U may need to use 1" wide wrapping.

* Stainless steel hose clamps.U can work out how many from this DIY.Bought from the same place $60 for lots of great quality Stainless Steel clamps!

* The usual tools to remove the headers.

* A blade to cut the wrap.

* Gasket goo and gaskets are optional,if U think U need them then get them.I didn't.I re-used the old gaskets with 'blue silicone',it's the same as gasket goo but much better,$20 a tube.There is another product that is copper and is better again but it's more expensive.

* Patience,for a good result.

Steps:

Put the car on jack stands and remove the header,just the bolts at the top there and the 2 underneath.Slide the headers out from under the car.Make sure U dissconnect or remove the 02 sensor first,be careful not to knock it if its still in there.

U can wrap ya headers while they are on the car but there is no way U can do a good a job as when they are off! The way to do it would be to kneel in front of the car,arms in at the headers.And obviously lay under the car for the 2-1 piping part.

Removing the headers is actually very easy to do.

Best to use a vice to hold them,while U wrap.If U dont have one,look to securing it somehow,it will make it far easier.

http://i774.photobucket.com/albums/yy25/beeza4/100_3290.jpg

First,fill a bucket of water and dunk ya header wrapping in there,this will all but eliminate those tiny fibreglass fibres from entering your breathing system and will make the wrapping much easier.Make sure U use gloves for this reason too,even a long sleeved shirt if ya keen.

Always start where the exhaust gases enter/start and work down/away from the engine.

The trick is U need to cut of strips of the wrap but how much? Basically I just felt it out and it worked out perfectly.I was using 60 - 90" lengths.

First,wrap it around 1 1/2 times and fix a clamp there.

http://i774.photobucket.com/albums/yy25/beeza4/100_3291.jpg

Good even wrapping,keep it tight,the recommendations is 1/4" overlap.Just keep it even,that's all that really matters.Mine ended up more than 1/4" overlap and it's awesome I feel.

http://i774.photobucket.com/albums/yy25/beeza4/100_3294.jpg

Tight tight tight!!

http://i774.photobucket.com/albums/yy25/beeza4/100_3295.jpg

1 done! U can see I wrapped right over the old 02 sensor bung hole location.If your 02 sensor is here,it's only reading 1 cylinder.

http://i774.photobucket.com/albums/yy25/beeza4/100_3296.jpg

Lets go!

http://i774.photobucket.com/albums/yy25/beeza4/100_3297.jpg

Every header will be different,this is how the 2nd pipe finished up,lets just leave that for now as we should be able to hose clamp that one with another one,the way the design is there.

Dont bunch it all up at the bottom,U still want it nice and evenly spread so no 'hot spots' appear.This can cause cracking in ya header.

Starting to warm up! Need some shade :D

OK,next piece!

http://i774.photobucket.com/albums/yy25/beeza4/100_3284.jpg

I wrapped one side then I wrap the other + the collector.2 pieces all up.U can wrap the collector seperately as a 3rd piece with 1/4" overlap if U wish.

http://i774.photobucket.com/albums/yy25/beeza4/100_3287.jpg

Clamps are where needed to hold it tight as!!

I cut a hole where the 02 sensor is :cool:

Other comments:

What a fun DIY!! Take off the headers,wrap em',whack em' back on,too easy and that means FUN!! :cool:

It took me 5 hours and I am super happeeeeeeeee with the results.Patience/time is the key to doing a good job here.

First Impressions:

I only done it yesterday but damn,I Love it.

* The sound - WOW.My car is so much quieter now,nice deep note,sounds solid,wow,impressed! That farty sound that was there at low rpm's is gone!!

* Performance - Pretty sure there is but I need more time.

Put it this way,I did a 0-100km/h run this morning as was like DAMN!!

EDIT: There's a definate performance increase,I knew there was after the first drive,just needed to make sure.

There certainly is.

* Another good thing about this is will protect ya headers to a degree in the event of a big whack.

EDIT: Added a header shield cause the car is looooow

http://i774.photobucket.com/albums/yy25/beeza4/100_1410.jpg

But the main reason I did this was to get the exhaust system sounding more solid,get rid of that farty sound at low rpm's and any performance gain will be a bonus.I definately feel there is and relay it on to U guys soon enough!

^^ Thanks Ryan,definately recommend it!

I would invite out the farm but I've already done that,about 10 times lol

Thanks Timmy,99% is planning,1% doing.So true.I have menatlly done this so many times in my head lol

U were right,I could hardly sleep,was to keen to drive it this morning hehehe

Can't wait to drive home haha,I'm taking beau's hilux tomorrow to work cause I gotta pick up the quad,dammit! lol

Gotta love,lovin' ya car aye :)

Nice work ! BUT. I have heard this is bad reading from other forums ? ?


heat wrap is BAD. It causes heatsoak into the steel, causing excessive fluctuation in the steel movement resulting in strees fractures of the martensite and austensite grade steel around welds(as well as making the non welded bits brittle) so its definitely a bad idea

This true ? cause I'am about to do my headers aswell

This argument will go on forever,so lets not go there.

Bottom line:

It happens.As with all warnings though,they get blown up into something that is bigger than what it is..

I was on d-series.org for a year,most guys on there have their headers wrapped and no one on there had an issue that I heard of.

It will always pop up but I believe it is not common at all.

The main reason why cracking occours is because the headers weren't wrapped correctly to begin with,this causes 'hot spots' or 'heat spots' which then leads to cracking etc.

The other is the headers were crap to begin with lol

Wrap them good,tidy,even and neat!

Nice pics!!! Especially stretching.

Instead of the Loctite 587 blue silicone sealant which goes only up to 260 ºC, you should use the 5920 copper one which goes to 371 ºC. Your exhaust will easily go above 260 ºC. I use Permatex Ultra Copper which is the same as the 5920 and goes up to 371 ºC as well. The Permatex version is cheaper than Loctite though.

Great Diy. im planning to wrap mine also. but cant find reasonable priced wrap from sydney.
Also how come you didnt blue silicon the header but ony the 2-1 join?
Some wrap kits have steel ties. how would they work compare to steel clamps? which is cheaper?
Thanks in advance.

the stainless steel ties work fine, just like the plastic ones except they can withstand the higher temperatures that plastic doesn't. if i could do it again, i'd probably use the ones beeza's used as you can get a tighter seal with them. just becareful when you use the the SS ties, and have to trim them not to cut yourself cos they are blood sharp. learn't from experience. awesome write up bretty!

Thanks mate,where the header joins onto the head is flat and the gasket is in tact,so no need.When I smacked the headers a few times before I got a H-brace that now protects it,it bent where the 4 meets the 2 and ripped the gasket where the collector on the header meets the exhaust piping.

I know the SS clamps sound expensive but it's something that U should do,like SHU says below.

Great DIY, i plan on doing this in the not too distant future... Even Spoon CEO Tatsuru Ichishima said that this is a must for those tracking their Hondas as the exhaust travels so close to the oil sump n doing this will reduce oil temp rise quite dramatically. +Rep

OH YEAH!

Great to hear.The extractors heat up the oil which heats up engine and then the coolant.After 10 minutes of flogging it on the track my car was overheating and I had to let it cool down,so on the 28th of june,the next trackday it will be good to note the change! I know there will be one,I'm very happy with all these benefits of having wrapped headers,no wonder I wanted to do this for ages!

There's a definate performance increase too,definately.

Thanks mate.

There certainly is.

Excellent DIY, rep point is on its way.

I can't see why there would be more performance. Can u explain this? Sounds like a placebo effect (I am a performance pessimist, and Hondas are notorious for giving low gains for mods). The benefits I can understand are less heat, therefore less chance of cracking at high temps... header protection and a different exhaust note.

Update: they won't let me rep u as I have repped u too recently :(

just use spoon heat tape on the sump
cracking only happens to cheap exhaust manifolds and bad exhaust fitment with no proper flexing points
usually with custom exhaust set ups

i have wrapped my exhaust in the past didnt do shit imo
caused more problems when u got fluids on it and would burn and stink the car out

nice write up brett but

I agree, i can't see any 'performance' benefits excepts minimising heat in the engine bay to a degree, but in bretts case it wouldnt have any affect because his pod is enclosed.

The only thing would be keeping the oil temp lower and minimising the chances of overheating.

And that loverly deeper sound mmmm mmmm.

You should mention taht if you wet the wrap before using it you can get a tighter seal on the manifold and this will make it easier to wrap - i was going to do a write up like this bu you beat me to it!

You are "supposed to" lightly dampen the wrap while applying it as it get its to wrap tighter and set better.

A few things to know about the wrap. Obviously the degree it affects your headers is going to be based on a number of factors. Such as, Timing, AFR, type of metal used in the extractors, environmental conditions (humid, salty).

I am one of the cases that had this stuff totally rape the face off my extractors to the point that they look an aborted child's face after its been run over by a an industrial, diesel powered cheese grater.

you can kinda see a before in this shot. These are pacemaker extractors on my falcooooon. Pacemaker is a well respected brand for these cars.
Ignore the dodgy hot air intake, this is when i was running the cam it, did a quick dodgy up to get the run in done before fitting the aftermarket ECU.
http://i346.photobucket.com/albums/p425/crazy2287/Image584.jpg

then my wrapping when i first done it (before i bolted back together)
http://i346.photobucket.com/albums/p425/crazy2287/Image513.jpg

and about 2 months later i developed a hole in my extractors. which quickly worsened.
I pulled the wrap off to investigate.
http://i346.photobucket.com/albums/p425/crazy2287/Image515.jpg
http://i346.photobucket.com/albums/p425/crazy2287/Image516.jpg

as you can see the damage was not only local to the "hot spot"

I used the wrap to try and lower under bonnet temps. it worked well. However you get a hotspot at the end of the wrapping. which happened to be my collectors. Also you can see this accelerated rust scale from the metal breaking down is from the heat and ingress of moisture from the wrapping material.
This combined with my high exhaust temps due to far retarded ign.
There is no doubt in my mind that this was caused by the wrapping.
i blasted, weilded and painted the extractors but they are not what they used to be. And they still have a damn leak..... *RAGE* Basically i spent like $90 to have something waste 2 hours of my time, a gasket, some gasket goop and slowly destroy my headers. Thumbs up. *lame face*
Obviously it's not necessarily GOING to happen. But seriously... why risk it?
a better alternative is simply some alloy sheet bent up into a "heat shield" Effective and nil negative side effects.

Performance boost??? Unless you have a turbo the performance boost is negligible. a 300-600HP car may pick up 5HP from wrapped turned length exhaust on a NA car. Something i doubt you'll be able to "feel" other then placebo. An FI car will experience gain because it's the velocity and HEAT energy in the exhaust that drives the turbine. If you wrap the pipes between engine and turbine then you will get more heat energy into the turbo.

so, IMO, don't use heat wrap unless you got plenty of money to be wasting... ESPECIALLY at the price they charge for the shite!

That said and done, It was a good writeup!

the trick is to clean your headers and spray them with Heat proof paint before wrapping them.
that stops them from rusting.

I usually paint at least 3 coats. Letting it dry between coats (or i cheat and use a blowtorch to speed things up)

Then wet them very damp to stop them from breaking when wrapping. Pull hard on them to get a nice even coverage.

Afterwards i normally start the car to dry up the water.
I've done this on 3-4 sets no issues. Longest lasting one was 4 yrs old.

crazy2287
17-06-2010, 08:02 PM
No, there is no splash tray under there. Why do you ask?

I like the sound of the heatproof paint idea! But i think it would take some pretty extreme paint to take the temps that it would get too under the wrap.
Its quite possible that had i had my timing issue sorted out then there would not have been enough heat there to cause it. However, reflecting on it and knowing what i know now, I would never fit this stuff to a NA car. And would only fit to a turbo if the primarys were going to be long and i was too cheap to invest in ceramic/glaze coating.

i'v'e had my headers heat wrapped. been to track and back nothing wrong with them. keeps temperature down dramatically in the engine bay. i dont see how they can cause a problem. even when your hitting the rev limiter after every corner around the track they held up well. nevertheless good writeup. try soaking the wrap in water first makes it easier to wrap around the headers.

hitoriko
17-06-2010, 09:13 PM
Limbo - thatas the best to do, hitemp heatproof paint, then do the wrap then let dray THEN silicon spray them because this also keeps the water out


No, there is no splash tray under there. Why do you ask?.

forget it

everytime i read these replies it makes me want to go outside and finish my set! but its FREEZING outside so i have to wait, worst thing is its halfway done just ahve to wrap 2 more pipes and im done!

The wrap keeps the headers hot! The hotter the exhaust gas, the quicker it will flow.

I wrapped my pit bike exhaust in it (I always burnt my leg on it) and then went for a 3 hour thrash with some mates, when i took the wrap off, the exhaust was a purple/blue colour all the way back to the muffler :D Before I wrapped it, there was only about 10-15cm of purple/blue

crazy2287

as the air becomes cool and slows down it will become turbulent and cause lower exhaust velocities and higher pressures. wrapping your zorst to keep in the heat on an NA car has little effect (though it dose have some)
turbos feed off the heat energy in the exhaust gases. so the difference is more noticeable in turbo cars, especially if it has long primary's before the turbine. after the turbine the exhaust gas pressure will reduce rapidly and causes the exhaust gas to cool. this is why large diameter free flowing exhausts are good after the turbo.

could be wrong, been a while since i did thermodynamics. i remember something about gases been thicker, due to the increased collisions of the gas molecules, at higher temperatures. but as long as the gas flow remains laminar there is no problems, thus the reason we try to keep velocity up. once the air becomes turbulent pressures increases dramatically. Ie after the turbine, so rather then trying to restore the laminar flow of the gases, we try to vent to air asap. this is why the turbo will ideally have nothing but a horn on the turbine exit. But i digress XD

That header on the falcon is mild steel is it not ? If it was stainless steel you shouldnt have any worries on it rusting away as stainless doesnt rust.

stainless dose corrode. it is just a lot more resilient.
Not sure of the grade of material in the pacemaker extractors. but definitely some kind of steel.

There are mixed results on header wrapping. As long as the grade of steel used in the header construction is high ie; stainless, you shouldnt run into corrosive/rust conditions. If you have mild steel manifold, id recomend a ceramic coating first, then glass wrap. Double the heat retention, and you also get the rust resistance of stainless.
