Have you tried wiping it? Could be exhaust deposits.

thanks! i did with good amount of rubbing compound but still... I'm more concern on the outside tip that becomes yellow overtime i got love with my full system except this part! carbon+yellow don't go well together in old book, wonder if others experience the same?

ITll do that from the heat and sun. Not much you can do about it. Its like proof you ride.

UV rays from the sun will turn it yellow over time

My Two Bro's turned yellow on me, to the point I want to get a new one. But this is what I found on the TwoBro's website.

Carbon Fiber Mufflers:
Always make sure the fiberglass packing inside is in
good condition and not burned out, as exhaust heat inside an empty canister
will deteriorate the Carbon Fiber sleeve. TBR sells repack kits (TBR part # 005-
1003 that include new rivets and repack material as well as a drill bit (#30),
making it easy to do yourself. Also, NEVER dyno test your bike with carbon
fiber mufflers installed - the intense heat and lack of cooling air can quickly
cause the CF material to burn. Two Brothers Racing does not provide a warranty
for burned carbon fiber.

I dont get it tho. It says to never dyno with it on. But wouldnt like a day of riding your bike in a hot summer heat cause more heat on the exhaust than a dyno run would??

Two brothers exhausts should NEVER be dyno'd. They should be used during high school parking lot wheelies, red light rev-limit bumps, and freeway top speed runs ONLY.

There is no air moving past it on a dyno to cool it.

I get your point though; it's stupid. So what do they expect you to do, just keep a spare stainless steel can laying around for when you go to the dyno?
