Default Header wrap questions

Im looking into wrapping my headers in addition to the ceramic coating thats on them and I am looking for input from people have used wrap on theirs.

Are there any particular kinds that are better than others? Ive heard the internet horror stories about it catching fire, any input here?

Basically I dont really know anything about it other than it holds more heat into the manifold and Im looking for explanations and info.

Thanks.

Make sure to wear gloves, a long sleeve shirt some sort of breathing PPE and soak the wrap. I got sick when I did my downpipe but it was on the car. If you do the wrap off the car it will be so much easier. Those fiberglass fibers are tiny and you will not see them flying around.

Defiantly what oguitar said, that stuff is itchy. For sure do it wet and maybe coat it with high temp silicone spray. DEI sells all the stuff. I actualy got all mine at Auto Zone but Summit Racing sells all of it also.

Also you can find the stainless steel tie wraps at Harbor Freight. I bought a bag of like twenty for 10$. The auto parts store sells like 3 of them for 10$. Don't forget to wear safety goggles. Some say not to wash your clothes in the washer but I am not sure if that is true or not. If you soak the wrap you will create less dust but you got to keep it wet. Then you got to let it thoroughly dry. Like Murphdog said paint the wrap with that high temp paint. It will protect the wrap a little bit better.

I have heard of heat wrap catching on fire but I have never seen any pictures of it. If your car is prone to leaking oil you might want to stay away from heat wrap. I think it is the oil that causes problems with fire.

yeah, an oil soaked piece of fiberglass sitting on your exhaust is not good.

I used hose clamps instead of those metal ties, i couldnt get them tight enough for my liking, def. wet the wrap because it allows you to make a tighter wrap. just follow the directions on it and take your time. Def. get the silicone spray stuff as well. the wrap will hold up better.

I got DEI on my header, up, dp. used just about one entire 2"x50' roll just for the header. one other roll for the UP & DP. DEI has a kit that includes 2 rolls a can of spray and some metal ties.

For peace of mind, buy a fire extinguisher and stash it in the car. If you have an oil leak and it gets onto the headers, you'll be in trouble.

With the headers already being ceramic coated in and out...is wrapping it going to be more hassle than its worth?

you will gain spool, but loose reliability of your headers..
i have a set of gt-spec headers swaintech coated and i just wrapped my up-pipe..
the headers are more likely to crack when wrapped

If you're worried about getting oil on the header, soaking into the wrap, and starting a fire, then after you're done wrapping wrap the header in aluminum tape. It lets the oil run/burn off without soaking into the wrap, I've had 2 oil leaks on my car, one coated my wrapped header, one was dripping on my wrapped uppipe. In both cases I had the aluminum tape on the pipe, the oil gave off some smoke but that's it.







I would highly recommend wrapping, the car will spool noticeably faster and retain heat better. I've never dealt with ceramic coated headers, but IIRC people have done tests that showed the heat retension was nowhere near wrapping.

What kind of Aluminum tape is that. Is it the roll stuff? Looks like a good wrap job.

heavy duty adhesive backed aluminum tape from home depot. Comes in a roll (like a roll of duct tape), roughly 3" wide and 50' long. I think it's used for patching holes in A/C ducts, but I could just be pulling that out of my ass.

Have you run these yet? How do you expect the adhesive on the tap to hold up to the heat?

If you look closely you'll see stainless bailing wire tied around the outside of the wrap to hold it in place once the adhesive melts off.

The header in the above pictures was on my car for about 6-7 months before I sold it to a friend (I needed a 2-bolt header). I wrapped my next header similarly, here's what it looked like a couple of months ago (a year and a half after I put it on the car) when I pulled the motor out to do a rebuild:

I def. think the wrap holds heat better than ceramic.

you can touch a wrapped exhaust real quick without getting burned, but you cant touch a ceramic coated one.

I did not think that aluminum tape would hold up so well. Good I might try this.

Thanks for the replies guys. I think I will try to wrap everything up...probably try to find someone who has done it before to show me the ropes. Kind of feel like i wasted my money on the ceramic coating now.

think of it as double the heat protection.

its not that difficult of a job. there are instructions that comes with it that are pretty good. the DEI wrap comes with a line so you know how far to overlap the wrap.

Cool. Which DEI wrap should I get? The regular stuff at the autopart store (dei brand) or get the new lava rock stuff?

I used the DEI titanium (lava) wrap and I liked it. It's hard to make a comparison because I have never used 'normal' wrap, but I found it to be very easy to work with. There was not very many fibers getting stuck everywhere and you don't have to soak it in water because it is super flexible right out of the package. DEI says you don't even need to spray it with the silicone spray because it is naturally repellent but I painted mine anyway. It does unravel really easily though which is annoying ( hard to explain without seeing it). I think it's good stuff.

i wrapped my stuff a while ago, so i used the regular stuff. I ordered the kit form Summit i think, it came with 2 2"x50' rolls a can of spray and a bunch of SS ties.enough for the header, UP & DP.

soaking the wrap lets you con form it and stretch it a bit around your piping.

there is a sale right now for the titanium stuff, don't know how the price compares to any where else though.

the aluminum foil, do you think its will also help hold the wrap better from falling off. cause how they get very brittle in time. it shouldnt start to flake or fall off because the foil is holding it all together i whould think. right
