Ok, so I now know I should not have heat wrapped the exhaust on my '03 54 when I put the CF devil slip-on, but I really like it, it seems to keep the heat off me & it looks cool. ? is: how bad is it, do I need to run out right now & strip it or can I wait till the outside temp drops below 100, or is it really even that bad?
This is my cherry poppin post so don't dry-hump me.

I have used my fair share of header wrap in my day (off road trucks). On cheap steel tubing, the wrap will promote rust by trapping moisture against the pipe. On your bike, you should not have to worry too much. Will get dirty looking very quickly though and starts to fray a bit after a few washes. It comes down to what kind of look you want. If you wait too long to remove the wrap, there might be some scuffing of the pipe due to crud that worked its way up against the pipe. Just my thought and welcome aboard.

I have used it on about every bike I have had but they were stainless... I was told that the pipes are Titanium & that it doesnt like to be wrapped. Are they really all Titanium.
I got the black wrap so it wont show the dirt and it looks good.
Thanks

You are right, the factory pipe is titanium. Not sure if the wrap will hurt it. I believe the Devil section of pipe is mild steel with a coating aplied to it. put a magnet to it. If the magnet holds, then it is steel.

Here is some useful info I found......Read the last line.......

Other ways of getting rid of the Heat

The exhaust heatshield got me to thinking about exhaust heat and its effects on the motorcycle and rider's "parts". Besides the stock heatshield foil that prevent the body panels from melting, has anyone tried an exhaust wrap or any other heat management devices? (heatshieldproducts.com) The exhaust pipe snakes near the shock, airbox, etc. radiates a large amount of heat that gets absorbed by these parts. Of course this heat has no beneficial effects except maybe in winter. I'm curious if anyone has any experience with wrapping the exhaust from past the header under the tank to where it/they hit the can/s, in other words, the section directly under the rider. According to the info on the webpage above, wrapping the pipe/s will increase exhaust gas velocity (maybe more power) and decrease radiant heat in the area that is wrapped but wouldn't that also redirect some of that heat to the can/s and heat up the tail-section?

My experience is limited with the wrap and it's on sportbikes. However, a section near the battery would certainly help keep the electrolyte from evaporating, a problem on the pre-GS versions of the bike.

Your best alternative is an aftermarket muffler, which will eliminate a ton of the heat. The stock cat/muffler arrangement on the older 650's is a real heat sink! I put the Staintune on and heat problems were solved.

No personal experience, but from what I've read, wraps do everything mentioned here AND wear the pipes out faster. Supposedly "JetHot Coating" has all the benefits as well as EXTENDING the life of header pipes, and has the added benefit of trick colors. One fellow who JHCed his Triumph header pipes noted a 10°-15° drop in external temp. From what I gathered, the excess heat (that the wrap hold in) heats the metal of the pipe higher each time it's run. Bottom line is that it fatigues the metal faster causing it to become brittle sooner. Keep in mind, too that we're talking about racing headers which, for weight reasons, use minimal wall thickness. On the metal of our pipes it may be a moot point. The JHC, OTOH, puts a thin ceramic coating on the INSIDE as well as the outside, so it insulates the PIPE as well as the surrounding components. The excess heat goes out the exhaust.

Dunno how much cooler the battery with the wrap would be. The wrap would probably need periodic replacement, as road splash would take its toll. I've heard of the wrap shortening the life on titanium pipes, but not stainless. BTW, it stinks for a while after it's put on the pipes.
