I love the look of header wrap. It's kind of an "old school, industrial" look. Looks mean! However...I'm not a fan of exhaust wrap after a friend of mine had his catch on fire after some oil spilled on it (67 mustang 289). Apparently, the exhaust wrap does not clean easily and oils/petrols stick to it. Looks "bad-a$$"...but I'd get them ceramic coated instead. Add to that the time and effort it would take to properly install the wrap with the close tube clearance of the down tubes and you might see the cost of ceramic coating to be a better option! Ceramic coating will help with the looks/corrosion resistance, but not the heat. Unless you REALLY need a heat barrier...I'd avoid exhaust wraps.

The exhaust wrap also tends to destroy the finish on the pipes once it is taken off. Have had several bikes in the shop that we have pulled the wrap off only to find the pipes severely damaged underneath (in one case the pipe had disintegrated to the point where you could push your finger through the metal). For this reason not a fan of the wrap (although it does look cool).

hmmm not the responses i was hoping to hear haha. i doubt mine will ever catch on fire that sounds like a one in a thousand kind of thing,and as for the erosion...well i can hope not. i am still thinking im going to go ahead and wrap ut, i think it looks to cool and i am down for the performance increase.. any ideas on how much wrap ill need, like how many feet

Could you describe to me how this could possible increase your performance?

Ceramic coating theoretically inproves performance as it lowers temperature, wrapping will act as an insulator - making it run hotter. Have also seen evidence of corrosion as a result of wrapping.

But hey if you don't want to listen to advice (after asking for it) for the sake of creating a look - that's cool no (pun intended)

The only benefit I can see of this would be on a car where engine heat increases intake temperatures. You want cold fuel and cold intake air for performance. I can't see a bit of benefit this could offer on a motorcycle.

As for higher exhaust temps increasing exhaust speed. That would work if you had an expansion chamber in the exhaust as with 2-stroke but it's a load of BS for a normal exhaust system.

i am new to motorcycles but as far as heat wrap goes on exhaust and cars i think it is all the same, if you want to install it, the posts about weakening the pipe is true, and if you miss a spot anywhere while wrapping, it superheats that part that you missed and makes it more prone to cracking and puts more heat than normal in the missed spot, if you are looking for a way to keep the heat in and maybe give it a nice finish i would go with high temp paint. i dnt know how hot the exhaust gets they make 1200 ans 2000 degree paint in vaious colors, but prep is key so the paint doesnt heat up and just flake off

As has been previously mentioned, the main purpose of exhaust wrap is to lower engine compartment heat by insulating the headers, thereby containing a large amount of the radiant heat... the problem is, this effectively raises the working temp of the headers themselves and, since they aren't designed to withstand elevated heat levels cycle after cycle after cycle, the metal breaks down much more rapidly. On a car, it may be worth it due to lowering the intake temp and possibly increasing hp (I've never seen dyno proof of that, but I'm willing to give the idea the benefit of the doubt), but on a bike it's useless unless you just like the look that much.

Ceramic coating effectively insulates the INTERIOR of the header/pipe as well as the exterior, reducing radiant heat while keeping the metal from damage, and it just looks ti4s, imho. I've heard there may be a slight hp increase due to some sort of "reduced friction on the molecular level" voodoo, but again, I've never seen dyno proof.

In short, ceramic coating ftw!

Peace

hey about these paints, how much do they cost, how much would the process cost, and what are some brand names of these paints, that sounds like a good idea to do what im looking for thanks for the suggestions

Less than 800F or 427C at the cylinder.

Go to Jet-Hot.com. Jet Hot has been the #1 ceramic coating specialist for many years in the auto racing business, recommended by many racing teams including Roush Racing and many others, specified by US Military. A proven product in a very wide range of applications. Developed for jet engines that have exhaust temps quite a bit higher than my Street Triple, and probably yours as well. I'm getting my Bonneville headers done this spring for less than US$150. Turn around time is about 1 week for most motorcycles. Request a quote from them directly. You will be surprised and they will send you a quote, a catalog and a video of their work.

I would think the higher exhaust temps hitting the muffler would cause it to degrade a lot faster. Also can the O2 sensor handle the increased exhaust temps?
Yes, to the first observation. For the second part, depends where the coating is in relation to the sensor. IMO, ceramic coating is a poor thing to do to this bike.

Once again all the negatives you dont want here are true if you do go ahead stop the wrap at the hottest point in the pipe if possible this actually makes power.

haha so f the wrap and ceramic coating. I think im going to go with black high temp. paint. i know some people say it will crack or chip towards the engine where its really hot. if thats the case then i guess a sand down and repaint will have to be redone every so often. no big deal

you can pick the paint up at any automotive store, napa , advance, autozone, and peboys just to name a few, and it comes in an aerosol can, i think about 8 bucks a can
