How much header wrap??
I think I'll try the header wrap on the stock pipe back to where my slip-ons start.
What size wrap should I get? I though about the 2" wide black but how long will I need to do the job. 50' to play it safe?
Also, I heard the trick of putting it on wet. Claims it makes it tighter once it dries. Can anyone confirm this technique?
Thanks

Couple of questions
do you have to take the headers off to install?

Take the exhaust off, much easier to get it really tight and heck of alot easier to wrap.
Install it soaking wet and pull it as tight as you can.
Wrap fron the back to the front so as to get the overlaps in the correct direction and keep stuff from grabbing the overlaps fron the front direction.

Got some black therma-tec 1"x50' header wrap sitting at the local napa for $40. Rated to 2k degrees and cheaper than SUMMITS delivered price. Took exhaust off last night and will wrap in the next few days when things slow down ...
After 9 years of this bike, I still love it but I'm wanting some new looks without investing more crazy money.. Got some other little goodies to install but I dont want to make my other bikes too jeolous!

Is this for heat sheilding only? i have read somewhere that it causes the ex gases to flow more freely in the system ands better scavaging the comb chamber due to incresed flow from hotter ex gases thoughout the system. Can anyone verify this or disprove im thinking or wrapping my headers and all if i can get a performance gain or crisper sound out of it.
i dont have a lower to protect...

Well, a few days ago I did the exhaust wrap. Turned out real nice and uniform but I wish I had 1 more foot of wrap as I was running a little short. If I do it again I will buy a 1"x50' pack for the main pipe and then a 1'x10' pack for the short rear cyl pipe.
I submerged the roll of blk wrap in water for a little over an hour before I started. On install, I pulled it as tight as I could and used SS safety wire and pliers at certain points for retaining its position. Definatly start at rear and work towards the exhaust port flanges.
After installation, I started the bike and noticed a slightly lower less metalic sound. Its a faint difference but noticeable. I let it run just until the heat started to smoke/evaporate the remaining trapped water in the wrap. For the last 2 days I did this to help dry the wrap completely. I havent rode it due to being in the middle of installing new rubber and a few other items. Its all dry but Its still gonna smoke for a while until its burned in. I suspect as long as the first 50+ miles are at highway speed, the wrap smokeing shouldnt be an issue. It was pretty stinky and smokey in the garage for only letting it idle for a mintue last night..
The wrap is extremely tight which is a good thing thanks to the water treatment. The black wrap was also a messy install when wet. I wore latex gloves to expidite cleanup as the coloring is like a graphite material and get pretty messy.
I'd post picture but I'm not that savy. Guess I need to open a photo bucket account or something?
Well, I hope this post helps anyone thinking about doing this. Now I just need to get her out and see if the jetting needs tweaked. I doubt it will though.. well see.
Oh, it looks tough too

The original reason is indeed for performance. You keep the gases hotter for longer, which as you say keeps flow faster and means that you can tune pipes more exactly for each cylinder. On the later TZ750 Yamahas, the #1 expansion chambers follow a course up and over the gearbox, are shorter than the other 3, and usually are wrapped in tape for this reason. It is only a side effect that the tape helps keep the LH side of the fairing from frying.
