hello.

i'm wrapping my header today.....i've wrapped it, strapped it, and cured it.

when i finnished curring, i noticed a few spots where it was realy plaible.

how should this turn out? should it be hard like a cast, or should it give a little.
i used DEI sealent. i put on like 4 coats, three thin, then a thick-o.

i used a heat gun to cure, 900=Lo; 1100=high

thanks.

no one has wrapped their header,eh?

maybe i need to wait a little longer for a responce....

I don't know about what kind of header you have, but my DC header so that if you wrap the header it voids the warranty... so something bad might happen, who knows.... I just left my DC header the way it was, and plus it was ceramic coated which is good for heat anyways...

Any header that you wrap will void the warranty. Its just because it traps in the heat, rather than letting it dissapate, and they don't want to be responsible for the extra heat cracking welds or deforming anything.

yeah, but this is a D17. it doesn't make that much heat anyway. the header is stainless steel. it'll be fine.

i'm asking about the silicone cover on the wrap. is it going to get hard?

i'm thinking no, 'cause it's been a few hours now. maybe when i put it in.

this header is for a EX. i have an LX. i have to add pipe extention to span the difference...i wonder if its a straight line.....

same here. I didnt really see the point in wrapping the header.

---"yeah, but this is a D17. it doesn't make that much heat anyway. the header is stainless steel. it'll be fine."

then i ask why go through the trouble of wrapping it?

Keeping the exaust hot for any car/engine will help some what. The reason is not to keep the engine bay cooler but to keep the exaust hotter...,.. why? because Hot gasses are lighter then cool gasses and thus take less effort to push through the exaust pipe. i know of some autocrossers that have the entire exaust system wrapped form header to tailpipe.

to reduce under hood heat.....i have a SRI, it'll help airflow, plus it'll keep the exhaust hot, making it less dense, flowing better.

hmm. I'm planning to wrap my header soon...

got the wraps, and the header... and er.. clamps...

I didnt think about using sealants... wouldn't clamps be enough if you just wrap it tight enough?

I guess I'll find out. lol.

most japanize auto enthusists wrap their complete exhaust. i haven't decided if i'm going any farther than my header; i might go a few more feet.

if i had a camera, i'd post a pic....

i don't need a warrenty, i bought it for $46. it's a
OBX-R stainless steel.

the sealent is to keep the weather out. it costs $7, from summit racing. it's good up to like 1500 degerees. i think it's worth it...

I rapped my HP header, it shouldnt get hard. BTW that stuff smells like crap the first couple of times it heats up.

ok.

did you just do header, or farther down??

how did you go about wrapping your header? like what did you use, process, etc

well....
i got some sweet wrap for cheap off e-bay.
i ordered some DEI stainless steel locking ties. (2500 degrees of resistance)
i ordered some DEI silicone sealant (1500 degrees)
i took my header, and started wrapping. i used 4, 8" ties. (one at the end of eachpipe going to the block)
i used 3 strips of header wrap about 3 1/2 feet, and one that was about 1 3/4 feet.
i bound all 4 strips at the bottom with another strip, about 1 1/2 foot.
i used three 14" locking SS ties; one at the bottom, one going arround the bottom and through the middle two pipes, one going the other way.
i sprayed sealent: 3 thin coats, 1 thick-o (used more than 3/4 of can)
then i cured it with a heat gun; on low(900 degrees) then on high(1100)
now i just need to get someone to help me put it in....

have you felt any kind of a difference, what does wrapping it do?

 
Rep Power: 0

it keeps heat in the exhaust pipe.

i need to get it installed. or i need to find someone with a pipe bender and a welder...

 
Rep Power: 368

heh I got the obx SS header too... and did u get the thermal tec wrap off ebay for cheap? it was like 20 something bucks each. heh.

I'm planning to wrap all the way down to my downpipe too...

search for a DIY on header install.. u gotta make sure u have the right tools so u dont strip or snap any bolts.. none of them are all very tight.. u just gotta be at the right position with the right tool to take them off.

its not like you're driving a power cranking monster its a D17 like they said whats the point of wrapping it? I advice to you is to stop watching 2 fast 2 furious and start listening to these ppl on this site there very knowledgable when it comes to civics and tuning

 
Rep Power: 380

thats the thing with a low power small displacement engine; every little bit counts. from getting the unsprung weight as low as possible to keeping the exaust as hot as possible for as long as possible... It all counts. Maybe not to some one who just runs on the street, but for some one like me where races are won and lost by .001 sec, every tiny thing counts.

*rollseye*

we know its a d17.

and no, the majority of people on the site aren't genearlly very knowledgeable.

sounds like the vin diesal speech in fast and furious if you ask me lol listen up kids try to understand that its just a movie i realize that wrapping your header might sound like a bright idea but so do so many other bright ideas that lead ppls rides to the junk yard

 
Rep Power: 368

dude why do u keep quoting that movie? and I haven't watched the 2nd one so I duno if they mention anything about wrapping headers there.. nor do I remember they mention anything about wrapping headers in the first one.. or anything constructive from that movie... cuz its just a freaking movie.

you think we're going to wrap our headers.. and think damn, its probably gain 50 hp now.. hey sure its only a barely 1.7 liter (1668cc) engine.. but I'm sure wrapping header will surely pump 50 hp outta this baby.. *smacks head*

damn I duno even know you got the movie into this entire damn thread.

its just a thread about someone asking on how other people wrap their headers. two people didn't think its necessary and a few others think "eh why not" and you went on and say "listen to the members on this board, they know about civics and tunning?"

and I can't get enough of how you kept mentioning that crap movie. damn.

i hate to tell ya, but i don't watch this crap. i want to reduce the under hood temptures, because of my SRI, and also, wrapping DOES create better flow. i don't know where you went to automotive school, but you have know idea what you are talking about. wrapping creates more heat on the inside of the pipe, which makes better flow. the hotter a gas is, the less dense it becomes, the easer it is to be moved because it weighs less, and there are less particles per square inch.(or centimeters)

in the 60's and 70's, when a tunner car was eather a monster car, or a VW bug, a VW tunner would do a different exhaust, header and complete pipe would get wrapped, because they were tring to get all they can out of it. they found that wrapping not only made their 90cc engine last longer by REDUCING TEMPATURES, but it also would add about 8-20 hp, depending on what engine you had.

i don't know why you are so emotional, i've already wrapped it, so why tell me not to? you think i wasted $50? well that's nice. it's already been done, so why be bothersome?

i need to install it still, so i can get some pics. then you can realy bitch at me....

Yeah, I would look forward to seeing some pictures uploaded...
