Header Wrap [Merged 3-8] thermal DEI headers exhaust

[98FWDSM]

ok, my cat is smacking against the heat shield underneath the car and it sounds like SH!T at full boost because it is rattling so much...would wrapping it in this heat wrap stuff work of should i just wedge a piece of metal in there so it cant move??

Thanks

I'd try tweeking the heat sheild or the exhaust hangers. You can also loosen the exhaust joints and try rotating then tightening for clearance.

My cat is making more noise than a baby's rattle, so I've also been wondering about the heat wrap thing. I'd love to be able to sit at a redlight and just hear my exhaust instead of that 'ting ta-ting ting ting ta-ta-ting'. :thumbdown

Our van had that rattle and it was a bad catalytic converter. I was embarassed to drive it around coz it sounds like it was falling apart. I had taken it to a muffler shop and had the cat replaced.

Heat wraps are bad for mild steel and stainless steel. Moisture stays on the wrap contributing to premature corrosion. I was also told that it it causes hairline cracks on the metal.

Get a test pipe, you're not in Cali.

 

[I-luv-em-all]

i was just gonna say get a straight pipe, if your on a budget and want some extra power take it out.....

See, that's what I love about these forums. The simple answer is usually the best answer. See the cat...kill the cat. Easy!

exhaust has been fully replaced with 3" Megan DP and a 3" Apexi cat-back. Now with the installation came taking out the heatsheilds and i was just wondering if it would be wise to totally wrap the exhaust ? Now sure if aftermarket exhaust give off as much heat being made out of different material but then again i am a over protective DSM owner



p.s

How come no one has added the word : "DSM" to the spell check !!

 

[RamenPride]

wrapping it will make it rust faster as it holds in heat and moisture. even stainless steel will rust, it happened to my downpipe.

 

[Defiant]

I'd recommend making shields instead of wrapping, because I don't like subjecting castings and tubing to a containment of heat that wrapping entails- at least, not on the street.

But that's just me. I'm old and superstitious.

 

[dsm4life]

well if i do decide to build heatshields later , it should be OK for now right, daily driver ? If i get stuck on highway on hots days , i just flip my toggle and turn on both AC fans to help keep air flowing (again over protective parent to DSM ). Just want to make sure it wont do any real harm to car.

Thanks guys....

 

[Warmachine91vr4]

I agree with defiant. thats an ass load of work and it will speed up the corrosion process. also where did you find that d/p i cant find 1 half deacent 3 incher for the old vr4 for any kind of low price i know off topic

 

[dsm4life]

search on ebay, i got megan 3" for 120 shipped to my door !

What would be more benificial, wrapping my fmic pipes with exhaust wrap (to hold in constant temperature), or "Cool Tape" (to reflect heat from engine off it)?

 

[gamingguru]

I dont really think that you need to wrap you IC piping, but if you decide to then you should use the reflective tape to help reduce intake air temperatures. If you havent wrapped up the hot side of your turbo with heat wrap then you could do that though as is beneficial.

I imagine neither is very beneficial. I use exhaust wrap on my lower piping in an attempt to keep the hot ass engine bay from heating up my charged air any more before it gets to the intercooler, but I am probably not accomplishing much of anything. I doubt the Cool Tape would stick to your piping for very long, or provide any advantages. The Cool Tape is more for insulating electrical stuff that you don't want to melt. I used it to cover the wires from my SPAL fans because they kept on melting, and also used it on my injector harnesses and EGT wiring. Most of it is coming off anyway though....

If you really want efficient IC pipes, get some aluminum ones made up, if you don't already have them.

hmmm actually youre wrong...using exhaust wrap has little benifit as it is designed to keep the exhaust hot, what you need is cool tape. the cool tape for electrical wiring is different than the one meant for intake pipes. the one for intake piping has a layer of fiberglass underneath aswell. ive use it on all my cars and it works excellent. you can feel the difference just by touching the taped pipes and the intake manifold. also they cool down awhole lot faster for some reason. the covered pipes always cooled down in about 5-6 minutes and the uncovered pipes were still pretty hot.

woah ive never seen that stuff before...nah cool tape comes in rolls of tape. its pretty cool stuff that you can use to wrap all your intercooler piping.

As far as I knew, DEI only makes one "Cool Tape." At least Summit and Jegs only carry one type. Like you said, it has a layer of fiberglass below the aluminum, and I believe it is more oriented towards electrical systems. DEI does however make what they call "air tube covers," which are designed for intake piping, as was pointed out above. These seem like they would be much more effective than wrapping the piping in a small layer of tape.
I am surprised the Cool Tape worked as well as it did for you. I still have like 30ft. left over, I might just go ahead and see what IC pipes I can wrap.

You can also get them ceramic coat too. Which is much better. Here is a website , locally in florida. www.hyperkote.com Thanks oj

yeah the one i bought, i got it at Kragens in the performance department with all the exhaust/header wrap stuff. it works pretty good, i would definetly recommend you wrap your intercooler piping with it.

 

[91boost]

Wrapping your IC pipes in anything is a bad idea. A simple temp probe will show you that the intake charge(before OR after the IC) is hotter than the engine bay temps on the outside of the pipes. So wrapping them will only block the pipe from cooling not only the pipe off, but the intake charge as well.

I can provide data if need be.

hey, I was wondering if the DEI Turbo Wrap is any good? Does it help keep the heat down and give back some horsepower? thanks Zach

its actually the opposite it keeps your turbo hotter so your gases flow more rapidly which in theory should produce more power.

 

[hystericfox]

My friend is using it in his (now single turbo) 3000GT. He's using it because the single is mounted over the transmission, relatively close to the hood and wiring. We figured we'd try this before we started making heat shields for everything.
