By wrapping your exhaust pipes it will keep exhaust gases hotter, in turn helping decrease gas density and increase flow, which can reduce intake temperatures and increase horsepower.
Prove. it.

nickkkkkIt has already been proven. Did you even look it up on google?

jbwifiBy who? some dumbass who buys this crap off massdrop probably. Generally speaking your try and keep your car cooler not hotter. This wont make your Honda Civic go any faster anyway.

nickkkkk"some dumbass"
There is scientific tested evidence on the internet. You could continue arguing it and make yourself look stupid, or you could actually do extremely light research into something before you disprove it, so you don't come across as the same type of person whom believes the world is flat.
"This wont make your Honda Civic go any faster anyway." Speaking from experience I would guess. but no, generally a stock honda would see no kw gain.

jbwifiWow "the internet", great source, I'm such a dumbass for being sceptical. Usually its the person claiming something to be true prove it, not the other way around. Again, show me an racing engineer or other specialist saying this thing is legit.

nickkkkkYou crack me up dude, I never claimed you were a dumbass, but heck I wont disagree with it, haha.
Theres no point in arguing with you. As my old man (quoting george calin) once said: “Never argue with an idiot. They will just bring you down to their level and beat you with experience.”

nickkkkkHey nickkkkk,
Hopefully I am able to explain the concept...
1-Take the most basic equation in Chemistry PV=nRT (pressure and temperature are related). *notice "P is equal to T" if you increase either one the other once will increase as well
2-Take the Three Laws of Thermodynamics - The second law for this application. (pppssstt there's really 5 Laws now. There's a cookie for you) **It describe how heat allows transfers from hot objects to cold objects (never cold to hot) - which is why engine bay temps always go up! **The engine combustion cycle is converting fuel into power, some energy is lost due to heat **If your engine is being put to work; that means, it will produce work but the work will guarantee to create heat- always
3-Heat transfer (how heat travels from high energy state to low energy state) ***heat travels outwards and will guarantee to raise the temperature of the engine bay. ***we want to reduce the amount of heat lost to the surrounding system -the engine bay for this case ***that increase of temperature if contained, the inside of the headers will increase pressure –recall 1
4-Path of least resistance (high pressure flows in direction of low pressure). ****with increase pressure the gasses will flow outwards to the outside much much faster - consequence of 1
5-Combine all of the four concepts from above and do not forget to think about the "*, **, ***, and ****" notes I've added. You should able to understand the theory behind why isolating (or containing) heat within the headers, by some method, will increases the pressure which will increases speed of gas flow (recall first equation again).
Also, this will keep engine bay temp way down! That’s the biggest bonus
You're welcome, from someone who actually takes science courses for an engineering field.

nickkkkkI failed pre-algebra 4 times, by the time I figured out how to study. I'm not "smart" I just learned how to learn.

Will.MelI wouldn't feel comfortable using Boyle's Law to justify the use of header wraps. The application in this scenario leads to an under-determined equation which means you need more equations to solve it. Also it is worth mentioning that using Boyle's Law constrains you to Ideal Gasses only. Considering we are talking about an open system and specifically, automotive exhaust, you are getting very far outside of what would likely be anywhere close to acceptable.
Trying to justify the use of such a product through theoretical means isn't really an honest, nor realistic approach to promoting this product. (to each their own) In personal experience, I and my colleagues have found using this type of product (header wrap) on turbo'ed applications was beneficial. In non-turbo'ed applications I've found it to be much much less effective compared to price and the potential downsides it may cause. Most notably being moisture retention between wrap layer and header material (mos often of which is metal). If you live in an extremely dry region this may be a non-issue. However, for most of the population, this is not the case, combine that with winter road treatments and you greatly increase your risk for things like rust. As with all things automotive related is comes down to pros vs. cons and your personal preference. (Note: We mostly use ceramic coating services, specifically White Lightning by Swain Tech Coatings, which can typically be found online fairly easily and are much more effective, but also more expensive as well as not a DIY option. Also, this wrap can often be found on Amazon for under 49.99 . (http://www.amazon.com/010127-Titanium-Exhaust-Header-Wrap/dp/B002R4U72I) Enjoy!
nickkkkkHey there. While these posts have brought upon several excellent responses from other community members, any further personal insults and unproductive arguments will be Moderated or Deleted. Thank you and have a good one.

jw333Jw33. Please do not spread misinformation even though you feel that you know what you are talking about. Your equation apply to gases in shocks.... NOT gases in headers. Shocks are contained in a volume, headers have an outlet.
jw33, I wanted to show the other user (nickkkkk) that it can be understood as soon as Introduction to Chemistry. Notice the other laws I've mentioned? Notice how the abstract laws -reference- back to the original? implying that it can be understood! Which is why I organized my comment in that order with those quotes. *I only explained the theory-behind-the-wraps. nothing more. I did not state any numbers or real world gains, there's YouTube videos showcasing that, and on video, documented, they have proved that it does work.
Why are you saying this is bad idea about insulating heat to increase temperatures and pressure is almost a bad idea, and yet you went ahead to show another companies solutions....who is doing the same concept . insulating headers. That whole portion is just odd to me. You wont trust a theory (let alone using the correct one) and then you mentioned another company who uses the theories I've mentioned. Very confusing and contradicting.
My response was directed towards nickkkkk who was rude at some other user NOT to justify - don't mix and match words.
If you want to reply to explain further to what your comments were referring to or on, sure, let me know. Please keep AlexPeterkin comment in mind as well.
