This is a quick review on the DEI exhaust wrap and DEI High temp silicone exhaust paint and sealant.
YOU HAVE TO DO THIS!!!!

As per my previous posts I high sided my bike and ordered a new fairing set from Auctmarts. On this site, I learned that heat shielding is a must!

This was my first attempt at wrapping so take a look at the pictures and tell me what you think. I wet the wrap then wrapped it tight around the pipe with ¼ inch overlap. After it dried I sprayed the exhaust paint and let it dry. After mounting, I started the bike up and revved it until the engine temp was around 220. The pipes smoked and smelled dreadful. After I stopped the bike I could touch the exhaust. Touching the exhaust, it’s incredible, do you guys think I need any more heat shielding to prevent melting of the pipes? Anyone who has wrapped their pipes, does this insulating ability go away over time or does it stay fairly consistent?
As you can see on the pics I wrapped the whole pipe from headers to can with a break in the wrap at the exhaust mounting bracket

Any opinions are welcome.

When you wrap the exhaust you keep the heat in the pipe instead of radiating out from it. When the exhaust is hotter, it leaves the pipe fast (warmer air moves faster) when the air leaves the pipe faster, it leaves more room for new exhaust gas, with this open area in the headers the new gas will not back up into the cylinder. It can add maybe a pony or two, but in reality it keeps the exhaust pipe cooler and since it exits under our ass it keeps the heat down under the seat

Sorry in my case, since I am getting after market plastics, I want to keep the radiant heat down and away from the new fairings

hey, looks good. did you use white wrap, then use the aluminum colored dei spray? i used white wrap, but im looking for white/clear spray. stupid ass parts stores only carry black. i did the back of the oem header and the oem mid pipe and tossed the heat shield.

Demon,

I think I might dump the heat guard and grind off the little support pieces on the stock rearsets. I used the DEI tan wrap, with the DEI black paint. If you are looking for aluminum paint check advance auto parts or pep boys, thats where I picked up the wrap and paint

i said fak it and went wiht the black dei silicone paint. its all done and waiting to dry. i also ended up coating the headers with the same black silicone dei paint. if it burns off, fak it.

ill make a new post wiht my new pipe and pics and all my new goodness i just did to my rstreet bish. time to eat some dinner.

I'd do this but i got the TI headers and pipe.

This stuff works great , I've noticed temps down a couple of degrees since using it . My Jardine headers (wrapped) only miss my lower fairings by about 3-4 mm , In this spot I also have the stick on heat shield but yeah almost touching and no problems in about 3000klm's. Only thing I will say is occasionally I can still smell them. :thumbsup:

here ya go. i let the bike get to temp, well almost (175*) and i touched the wrap. warm, but not too hot where i couldnt touch it w/o getting burnt. no more heat shield and no more trim piece.

heres a couple pics. in the last pic, you see where i sparayed the headers. nice clean black look and havent burned off...yet. hopefully they stay this way to help keep temps down and away from my hannspree plastics.

FOr the cost and looks .Ceramic coating is WAY better.. Had mine done in black .Wrapping cost 65-80.00 ,coating cost 115.00

i actually like the look of the wraps




I believe that the wraps are good to protect various 'items' from heat, but not to hold the heat in the header. For example: you can use the wrapping for the protection of fuel and oil lines, wiring, covering a starter motor, etc.

Cool air needs to be around the header, and insulating it with a wrap to hold exhaust heat in makes the header material temperatures near molten. When you wrap the header you trap the heat in the header, but also in the material that needs to breathe to dissipate heat for it's own survival.
But, when the header is not allowed to cool so as to dissipate those extreme temperatures that the wrap is controlling, you have now developed a heat absorption that compares to thermal friction. This causes temperatures to continue to rise beyond the normal exhaust gas temperatures (EGT's) the header material was designed to withstand. This holds true as with most any insulation.
The EGTs stay the same but the properties of the header material changes by amplifying the temperature due to the insulation.

Pics look good, I wrapped mine from the headers back and once the burning of the new wrap burned off they were good to go.

making the gas hotter expels the gases faster. the idea behind ceram and wrap is to expel the gases quicker not protect the header or parts except on a twin rear header where it burn the shock and makes it fade IMO
