It is mostly a matter of looks, it will keep you from burning your hands, feet, does hold temp longer on cool down which will keep exhaust valve from warpage (Although I have never heard of this happening unless NO exhaust pipe was present).. But it won't hurt anything, will trap moisture in wrap and cause surface rust on pipe wrapped...

it will trap moisture... but only while the bike isn't running.

That exhaust gets hot enough to evaporate moisture out of the wrap pretty quick. wrap will accelerate rust if it gets wet while the bike is cool.

In some headers, wrap keeps the pipe hotter, allowing gasses to move faster giving a boost in performance. Our header doesn't get any performance benefit from being wrapped; it is purely aesthetic aside from preventing burns (though burns will still happen if something touches it for a longer time, the wrap just slows the rate at which heat is transferred to whatever touches it).

I've got mine wrapped so that I could ditch the heat shield and to cover up some blemished on the pipe that were already there. It also prevents me from burning my knuckles when working on the engine hot, BUT i still burn a bit of rubber from my boots off on it if i rest my boot there (because I removed the heat shield by the right foot peg).

Reply #3 - 03/29/12 at 11:44:20 I tried the wrap but when it gets wet the steam doesn't smell that great. I had the header ceramic coated instead and removed the heat shield. If the high temp black paint wears off of my MAC muffler to any great extent, I may do the same to it.

How expensive is it for ceramic coating and how does that hold up to use/abuse?

I had the ceramic done in 2007 by a guy I found in Irving, TX. He was retired and had converted his garage to a workshop with large ovens (kilns?) where all he did was ceramic coat stuff as a part-time business; mostly custom exhausts but he did engine blocks and such too. I think he's since retired fully and doesn't do it anymore as his web site is no longer functional and he was probably in his early 70's when I had this done. It ran me around $50 at that time but it was almost 5 years ago. The stuff is extremely tough. The guy took a couple of pieces he'd coated previously and banged them together pretty hard; there wasn't a scratch or chip at all. It definitely cuts down on the radiant heat too. Below is a link to that thread. When I was searching for it, I found other, more recent posts where they said it was about $100.

Reply #7 - 03/31/12 at 07:31:11 If you have a nice shiny header pipe and want to keep it that way, don't wrap it, because it will take alot of cleaning to restore the chrome if you take the wrap off. Otherwise, wrap it with DEI titanium.. It won't cause damage to the engine.

Even that may not be enough. My header was "blued" to a honey color before I added the wrap. When I removed it weeks later it was blued very badly. The is was one reason I began looking into ceramic coatings.

I asked you first.

Exposure to moisture while running is mostly irrelevant, anyway, since it is exposed to a thousand times more moisture (duration) while parked.

bah, i disagree, but I don't think arguing my point will get me anywhere.

I am lucky enough to park in a heated garage, so my bike isn't exposed to almost any moisture when compared to riding in all weather conditions (including plenty of rainy days here in Pittsburgh). Last year I had my bike die on me because I tried to ride through a puddle that hid its true depth to me (hint: it ended up being significantly deeper than the opening of my exhaust). Even sitting in a garage with light humidity for a year wouldn't added up to that amount of moisture, not that turning the savage into a submarine is a typical use case.

besides, unless water is actively getting on your bike when it is stored (at least put a cover on it, come on!) it wouldn't be much different with or without wrap.

if you don't like the look of it, fine, so be it. i can take that as an acceptable answer. if you argue that our bikes' triple-walled header is going to rust out orders of magnitude faster, i just don't buy it. faster, sure, but not that fast.

The fact you don't buy it just means you don't understand.

Do a little experiment. Go get a piece of steel tubing and wrap maybe 6" of it in cloth, or, even better, if you have some exhaust wrap to spare, use that. Put it on shelf near where you keep your bike, and leave it alone for a few months. After that, come back and see which is corroded more, the unwrapped part or the wrapped part.

On a bike with a header sweater, riding around in the rain will have almost no effect at all because the water is steamed off immediately. It's the long term effect of a very tiny bit of corrosion each day (temperature ups and downs) caused by moisture being trapped, condensed, and evaporated by the exhaust wrap that discolors and even corrodes a wrapped exhaust pipe.
