I have heard this as well, but it didn't happen to my 2Bros when I had them. I think the trick is to make sure you repack the cans at the recommended intervals, as this helps disapate the heat better.

Curious about this as well.

Buddy had carbons yellow on his cbr600. Don't remember which pipes they were. Sounded amazing. Wasn't really noticeable unless looking really close at the right angle from the sunlight. He rides near redline at all times even during a liesurely cruise. Don't know if the heat did it, or sunlight or what. Like I said before, pipes still looked good, but the resin or whatever's over the carbon got SLIGHTLY opaque and golden. He had that thing since junior year, so about 5 or so years before either one of us noticed.

I just finished reading a post about this. RSW is correct, if you re-pack these , it should not be a problem. I have a friend with Two Bros carbon fiber that are turning yellow, but the pipes are about 7 years old, was on a used bike that was used only for racing. The pies have never been re-packed. Two Bros offers all of the parts necessary for a re-packing , and I think it costs around $20 ish. I am sure that Leo Vince probably offers a kit as well.

Yes it is true. Pretty much because of the UV rays from the sun.

You want to know why, here's a post from a member who specializes in the field of chemistry.

So if you live where the sun shines a lot, it's not recommended that you get carbon fibers, you are better off with titanium or stainless steel. Just another thing you don't have to worry about.

i know that all carbon fiber turns yellow. but cant find any pics of it turned yellow. just wanted to know if it looks real bad or is it kinda hard to tell unless you are looking real close to it?

i have the C/F and so far so good. I clean the bike every 3 days or so. If it rains i clean it after i use it, otherwise just a dusting to keep the shine.

I talked to a rep at 2 bros a while back about repacking. V twins need to be repacked more ofter due the fact they run hotter. He recommended repack around 5k miles for the FZ or just swap with the left can and repack at both at 10K. Makes sense since the right can does 95%of the work.
High heat is real hard on the CF.

how the hell u change the cans over?

my leos are 2 different size's seen the devils pipes are the same!

also the pipe work is different




the carbon fibre yellows due to the sun and cheap carbon will yellow faster
and it is usually the clear coat of the part that yellows not the actual fibre!

2bros cans bolt to the thier pipe and can be used on either side. Guess paying the big $$ made it possible.

 

[Red Wazp]

Geez I need to use spell check- the cans bolt to THEIR pipe. sorry

Geez I need to use spell check-

Or "EDIT" :rof:
See down there on the bottom right of your post, there's a little box with edit in there.. Sorry, couldn't resist :spank:

Its the resin that goes yellow but if its clear coated in uv protection clear coat or made with uv resistant resin no problems

You can just flip the Two Bro's I don't know about the other aftermarket exhausts for the FZ6.

I also read some where that some companies don't recommend or guarantee their CF cans when you push them on a dyno because they become stressed from the heat. If you have CF cans and get dyno'd maybe you could add a fan to help keep them cooler.
I didn't worry about it with aluminum cans. [ame=http://www.youtube.com/watch?v=69L2vAhOymg]YouTube - FZ6 DYNO[/ame]
