Hej "Russer60"

Hvor i DK holder du til ??

Havde du tænkt dig at lægge CF/kevlar på som "skinning" på de eksisterende potter?

Jeg har lidt erfaring med CF og endcaps til MC udstødning o.s.v.


In english, so as not to be too rude ... BigGrin

Were you thinking of "skinning" the existing exhaust cans with CF/kevlar or just wrapping the downpipes in Kevlar?

Usually "skinning" the cans will work, if you use high temperature Resin like the 180 deg. from EC but only on the rear most parts of an exhaust.

It will insulate the "can" and create higher temperatures inside the can, and it will change the sound a bit ..

If you use an infrared thermometer, and measure the outside temperatures of the cans immediately after a hard run in hot weather, you can find out if the Resin will take the heat.

In my experience you will need an outside temperature below 120 - 130 degrees C for the Resin to be able to last. I have not yet seen exhaust end cans on any bike that ran hotter than that, except in confined areas and special circumstances ( exhaust routed up under /throug the tail section of a bike or under very enclosed fairing parts.

If you wrap your downpipes in kevlar or glassfibre, the end cans will get much hotter, since the downpipes will not cool the exhaust gases as much.

Do not adjust our mind, theres a fault in reality :-)

What's the purpose of the kevlar? If it's for heat shielding, you can buy exhaust wrap which is basically just a narrow fiberglass tape (narrow but thick) that you wrap around it dry - no resin. I don't see why you couldn't do it with kevlar if you wanted it yellow instead.

Most fabrics will withstand the heat, the problem will be the resin system you are using...
there is a high tempeature epoxy resin from easy composites but not sure it will stand those extreme temperatures from an exhaust...
sure some other members on here will be able to give you more information

Sorry for any misspelling im am not that good in English. (From Denmark BigGrin)
I am wondering if I could put kevlar on my exhaust pipes (Yamaha fj1200 with XJR1300 pipes) Can it withstand the heat? 
Is there any thing that I have to look after if i will try?
