Wrapping My Headers (I Should've Done This a Long Time Ago..)

[@undeadexile2485]

for those who try this DEI header wrap, wear a long sleeve, gloves, and a mask if indoors without ventilation. this stuff itches and will give you a sore throat if you inhale some of the little fibers. otherwise its great stuff.

[@johnnymula2305]

Not even remotely close to the truth. Unless you got some really cheap crap. Ive wrapped at least a dozen headers and motorcycle exhausts. No gloves. No mask. Shorts and t shirt. Never had so much as a single itch.

[@simplyvortech4616]

I don’t understand why this was satisfying to watch 😂

[@jeffbowman8265]

I CANT STAND THE ITCHY FEELING!!! Why do they make this crap like that?????

[@duckybuttracing6297]

Cause fiberglass is the only thing that's flexible to wrap with if u would wet it down and use gloves it's really not bad

[@willparker3170]

Brandon's notch supercharged 5.0 dude this wrap isn’t fiberglass. It’s titanium and basalt fibers

[@CamiloSantana]

a bit of advice i was given was to wet the wrap so it'll stretch more and be tighter once it dries.

[@JohnVesely]

This type of wrap is a basalt material. You don’t need to wet since it’s already flexible. But a fiberglass wrap you’ll need to wet before applying.

[@CamiloSantana]

cool. good to know. and i'm guessing you don't have to wear dust mask. i'll buy that next time. thanks again! much obliged.

[@CamiloSantana]

and i see you explained that verbally at the one-minute mark. i knew i should have slowed the video down. ... rushing through research /facepalm

[@LandonWilks]

This is a great video man👍🏼 Keep up the good work!

[@lopezjreleazar]

How many feet did you use for both headers?

[@Wbroach24]

Well...technically if you breathe in to much of that dust, you could potentially conract: Pneumonoultramicroscopicsilicovolcanoconiosis from inhaling microscopic volcanic dust. Or Black Lung if you dont want to spell that out from memory like some weirdo 😂😂.

[@jacksmith3189]

Good information I’ll give it a try Thanks

[@guidosarducci3047]

Probably the best or most thoroughly done video I've seen so far. Going through all of the u tube videos I can find or until I feel ready to attempt. Wanted to thank u for posting. U did good. I liked & subbed.

[@amrikjaswal76]

Great video...thanks....going to wrap my headers on my 69 442 tmrw!

[@Grenadieros]

Galvanized wire would do as an extra insurance. No problem at all,even some producers of ''heat shield" products use it.

[@johnnymula2305]

I used a soldering knife to score my header wrap after cutting it. It kept it from fraying.

[@Wbroach24]

My first thought was a hot knife. I don't have one yet, but I will before I take my headers off to put a new starter wire with heat sleave on and wrap my headers so I don't melt my starter wires and plug wires 🙂

[@cliffordhall7291]

this looks like sel-temp furnace material, nasty,use respirator& gloves

[@duckybuttracing6297]

Most of these wraps have fiberglass if u would wet it and use gloves it's really not bad

[@makantahi3731]

my 304 rusted as cheap iron

[@ati573]

How's ot holding up and did it cool your engine bay, any performance improvement?

[@MarkCarr331]

you did a great job. was one kit enough for both headers or does it require two kits?

[@JohnVesely]

It does both headers

[@KingLoyalGaming]

How many rolls did you use ?

[@QuinntumAZ]

Whats the temps on the headers after the wrap? And its been a couple years, hows it holding up?

[@TheDailyAmerican]

I was just watching our older tune videos just a few minutes ago. Hope the tune is still treating you right man. Cheers!

[@jacksmith3189]

Good information Thanks

[@MrTimdtoolman1]

The wrap looks good man. It looks like you did a good job to me. The headers must really get hot compared to the stock manifold?

[@JohnVesely]

Yeah they get really hot, you could feel the heat just by standing next to the truck.

[@makantahi3731]

no and never again

[@fasnuf]

how many rolls to wrap both headers?

[@scottdeeter6164]

Just wrapped my headers last night one 50 foot roll per header

[@sethelable]

How is it holding up after about a year?

[@JohnVesely]

Really good. It’s not showing any wear other than where it was rubbing on the frame. It looks like I just put it on yesterday still.

[@DonCatherman]

Wear gloves the fiberglass gets ichey,,,lol..he just said that.. your job dose look better then DIY guys job....I did mine a while back..came out good...I'm going to do the pipes under the car as well.X pipe exhaust on drag car,,floor gets hot it should help a lot..you can get header rap pretty cheap on eBay,,2,, 50 ft rolls with 20, ties for like 15 bucks is what I paid..it's well worth the time an effort...good vid kid..good luck guys...

[@DonCatherman]

The black turns alittel gray no big deal..yeah it smokes a bit..for a while till it's all burned off... don't bother painting the headers or the rap. It will burn off anyway..an it smokes forever untill it's burned away ,,don't waste ur time or money on header paint...good job kid .....

[@anthonypapa8676]

I see the video is 3 years ago what are your thoughts now

[@Vadrun]

I know that this vid is old but maybe someone will reply xD You mentioned spraying silicone on the headers to make it better. But isn't silicone flammable? I know that the wrap will keep temp low, but still - low enough so anything sprayed on it won't catch fire?

[@snowyrt]

Should I get the small roll of the big one to wrap both longtubes headers

[@orbitaljellyfish808]

Did the wrap make the exhaust sound any different?

[@Beaches_south_of_L.A.]

I liked your video man. You did a good job. Cool truck.

[@jadentv1939]

Sir , how many meters your thermal wrap ? Or how many feet

[@elseco2341]

Do I still need msd wires after wrapping

[@nx.garage2155]

2 years later, how are the header wraps holding up?

[@elseco2341]

Do I still need msd wires after wrapping

[@MW-jx1hj]

Any follow up? How has the wrap held up?

[@Zeroxmagic]

How did it hold up after 2 years?

[@angelobovara317]

Yeah. Dang good vid. Liked

[@123nova87]

Think I’m gonna do this for my fender exit schoenfeld headers on my nova. Cheaper then stripping and ceramic coating which is 250 plus from a shop around me.

[@jasperluisaenlle4198]

is that a 1 inch or 2 inch wide?

[@steventahuri8013]

Stainless steel does fail when too hot. Race teams use the highest grade possible and ceramic them for a reason... this is tech from the 60s that people still use... unbelievably. "Hey KZbin, today I'm going to show you how I'm going to destroy my headers and how you can do the same to yours". Also, they are a huge fire risk if oil gets on them.... buy you knew that right?

[@kurtnulf3362]

Yes and ceramic coating cost 300$ dollars for a set of exhaust manifolds I think I will try the wrap first

[@gregmf9427]

Too much “heat Control” What does that mean? Are you sayin it’s Bad to keep it to cool? I don’t follow?

[@JohnVesely]

If you wrap the header too thick the header will hold too much heat causing it to become brittle. Yeah the engine bay might be “cooler” but it’s not good for the piping

[@JohnVesely]

Go follow my Instagram @johnvesely_youtube to see behind the scenes or posts about new videos! Header Wrap I used- DEI Titanium Header wrap: amzn.to/2DXydca

[@elmajicovalluco]

John Vesely how you doing john im in a bind between putting on a cam or not for the simple fact that im afraid that my transmission will give i wasnt going with anything big i have a 2008 silverado crew cab with about 65,000 miles on truck i was thinking putting 220 220 cam with dod delete kit with of course a tune have you had any issues with your transmission? Or what have you done to prevent excessive beat down on your tranny i was maybe thinking install a servo and a transmission cooler?

[@elmajicovalluco]

John Vesely thanks for the response bud there is hardly any videos on these subjects on youtube like you said in you last video but yeah i am aware of this issue i might just do a dod delete kit with spring and lifter kit with a tune for the time being since this truck is my daily driver and only was going with cam and performance option since my lifter alreadt gave out common issue on 5.3 motors im sure your aware of that nut akyways keep uo the good videos buddy you got yourself a subcriber right here my man! All the way from south texas!

[@JohnVesely]

If your going to go through all that trouble I would cam it while you have the heads off and the engine torn down. I have the 220 cam and before I put the headers on it’s was noticeably faster than stock, but it only gained 35whp so it wouldn’t be too harsh on the tranny since it’s not making full power while the stock exhaust manifold was choking up the engine. But once you put the long tubes on to let the engine breathe you may see another 20-30 hp gain.

[@elmajicovalluco]

John Vesely mmmmm yeah that why i decided to go with the 220 and also true since the are installing a new stock cam with the dod but like i said just scared since its my daily driver you know bud

[@JohnVesely]

As long as your not hard on it everyday and just drive it normal it should last. Plus your truck has pretty low miles for an 08 so that’s a plus. And whoever you have doing the tune just have the shift firm but not aggressive.

[@L-Noble.YT_Hi.Res-Soundminds]

If you have some common sense then you know that too much of something is bad. That's why heat is good up to a point. The exhaust manifold already gets hot as shit so why would you make it hotter? Some headers start to glow red, do they need to get hotter? You can probably wrap or damage the primaries when using this stuff. Sometimes you can't just go by what you hear. If anything the best place to wrap an exhaust is way further down the pipes like after the catalitic converter to keep that part at a higher temp because the further you go from the motor the cooler the e exhaust gets. Another thing is if you use this wrap the header gets hotter and that means the heat is transfer the the head. I mean the header is bolted to the head and most heads are aluminum. Aluminum transfers heat very well so this means the head will also get additional heat from the header.

[@Shaunemayfield]

I don’t think you understand how these work. Hotter air moves faster. With wrapped headers the air moves faster through and out the exhaust, the opposite of what you presume. With unwrapped headers the air moves slower therefore heating the pipes more and move that hot air into the engine bay. Slower air means increased back pressure pushing the heat back to the engine, again the opposite of your explanation. Wrapped pipes will decrease heat back to the heads, that’s why this has been used for dozens and dozens of years.

[@L-Noble.YT_Hi.Res-Soundminds]

@@Shaunemayfield dont wrap it, ceramic coat it. You'll be glad you spent the money on it.😄🙏😃

[@shaun73084]

Hey John, looks good man, I was curious about something though. If having the wrap lap more than .25" causes excessive heat buildup and essentially causes the pipes to become brittle, then how does double wrapping over them from the collector to where they separate not cause a similar issue?

[@MrRoyalfelix]

shaun73084 I would guess because it's not 100 percent double wrapped goes around a section of the pipe again but not completely around kinda like if you cover it self with a sheet then only cover half your body with another sheet you wouldn't get as hot... hope that makes sense...

[@skaterdude123ify]

Did this crack your headers in the end?

[@JohnVesely]

No, they are still fine

[@longaster]

Did it quiet the headers down at all?

[@JohnVesely]

Yeah it quieted down some of the header noise and engine noise. Before the wrap it sounded like there was a constant exhaust leak because the headers are thin.

[@chocolon1129]

Hey man, any update you will like to share? Thinking about getting them for my truck. Thanks

[@JohnVesely]

The header wrap is still holding up. But I have noticed there is rust on the pipes alittle. As long as you don’t get them wet it should be fine.

[@chocolon1129]

John Vesely thanks man

[@frankosmith6718]

Titanium is one of the most expensive metals on earth. How much was the 50-foot roll?

[@JohnVesely]

It’s not actually titanium lol. It’s basalt which is a type of rock. But that’s what they call the wrap

[@fasnuf]

They call it Titanium because of the color.

[@d1prospect15]

FYI you don’t need spray on titanium wraps only non titanium wraps can be sprayed 👌🏾

[@PapodeArmas]

i sprayed mine, dont think it will harm it thou...

[@DanMcD80]

then why does dei make a silicon spray for their titanium wrap?

[@gregmf9427]

That’s like wearing a sweater during the summer

[@JohnVesely]

Well yeah kinda, all the wrap does is insulate the heat from the pipes from going into the engine bay.

[@Shaunemayfield]

Hotter exhaust moves faster. When they’re wrapped the gases move quicker. Unwrapped the metal pipes are absorbing the heat more and putting it into the engine bay. So exhaust wrap eliminates engine bay heat AND increasing exhaust gas exit speed (increased flow)!

[@streetplatoon562]

Was that copper gasket maker at the end of your collector ?

[@JohnVesely]

It’s a high temp rtv, it’s helped with the gaskets as far as leaks go and it’s lasted a while now

[@streetplatoon562]

I need to add some to my headers at the collectors, I have the permatex ultra copper gasket maker... hopefully it will do the trick.

[@The96jaime]

Go e85 🤔

[@dennisfook2717]

Wet your heat wrap

[@AwesomeMillerChill]

Only on fiberglass you need to wet it

[@guidosarducci3047]

Oh yeah one question please...How many feet did it take? Thanks

[@CrazyCowboyBuilds]

I did shorty aftermarket headers on a Ferrari F430 and LS motor shorty eBay turbo headers with the lava wrap on eBay. Really itchy stuff but wet it and took one roll almost per header so get two rolls. You can always wrap downpipes and other pipes for the turbo system 👍🏼

[@guidosarducci3047]

thank u for reply. Build sounds killer man!

[@CrazyCowboyBuilds]

Guido Sarducci thanks. Check out my IG Car_Building_Inspiration I just wrapped an LS header last night. 👍🏼

[@Peacetoself]

Great video thanks. Was the 50ft roll enough for both headers?

[@JohnVesely]

What I can remember I think so. I did have some left over.

[@willparker3170]

I wrapped a set of long tubes for my C10 the other day all the way down to the end of the collector and it took 140 feet of wrap. Buy the stuff off amazon it’s so much cheaper

[@HoustonRocket281]

Very good info bro I’m doing this after I get my headers and what next on the truck this year you want to get done ?

[@JohnVesely]

Hopefully get a new torque converter and just freshen up the truck and undercoat the frame.

[@kdelmundo2299]

I was thinking of wrapping the exhaust pipe on my Tahoe. It's the pipe right under the transmission pan to keep the exhaust heat from radiating to the transmission pan to keep my transmission pan and transmission oil from getting hot. Would thst be a good idea?

[@JohnVesely]

That’s what I did, I think it helps but I haven’t run it without the wrap.

[@walterschreiber3505]

I own a 2013 f150......I put stainless headers on it and hi flow cats and stainless y pipe I have now wrapped my entire exhaust system and wow what a big diff......underhood Temps way down and the y pipe does not heat up my tranny pan........I also used vht flame proof paint on all of it......lot of work but soo glad I did it

[@walterschreiber3505]

I would paint it too.......it helps protect the wrap........also I used reflective heat tape on my fuel lines........made a difference in Power

[@baldotorres1976]

What header are they

[@JohnVesely]

Texas speed and performance headers

[@baldotorres1976]

John Vesely thanks

[@JohnFrancoNH]

Great video man. You dont have to use the silicone spray on titanium wraps. Its only for non-Ti wraps. Thanks for sharing!

[@codyjackson7724]

From what I've learned wraps tear your headers up and that it's better to get them paint with ceramic

[@matthewwilliams4317]

Did this quiet the valve train noise down? Great video by the way.

[@seanoleary1979]

Ahhhh... he didn't wrap the valve-train, he wrapped the exhaust headers!

[@BoostedOnaBudget5]

did you have any left over for the y pipe

[@JohnVesely]

Yes

[@Boofedit]

You’ll need a new exhaust in around a year or so

[@NaviPureMusic]

themusicmastera380 how is that please explain this

[@milenkogt]

@@NaviPureMusic not necessarily will he have to replace lol. Its stainless,probably 409 and not mild steel. The reason DEI states to overlap a 1/4" in all areas as best as possible to help prevent to much heat entrapment which could potentially cause the substrate/base metal to become brittle. You dont have to, but you can apply the silicone coating to the header primary surface and the wrap itself to help prevent water retention and it helps keep the wrap together. The titanium wrap from DEI is made from Basalt. Basalt is a essentially volcanic rock molten down and extruded into fibrous glass strands. It is also used to reinforce concrete in some applications. Bottom line, make sure you base metal is of good quality stainless and follow the wrapping procedure as best you can since each application is different. Otherwise, you can utilize ceramic coating like Zircotec or Swaintech coatings which uses an aluminum oxide or zirconium oxide powder transferred via plasma spray to the metal substrate which reduces thermal transfer as well as provides corrosion resistance.
