A friend of mine has one of those Chinese scooters and asked a question regarding a carbon fiber exhaust:

Q:About 5 months ago I purchased a Carbon Fiber Exhaust (HP150)from PSF Motors. It came with a chrome pipe which is now totally discolored from the heat that flows through the pipe. I am about to purchase a new chrome pipe from Scootertronics but DO NOT want it to get discolored again. Does anyone know how to
 avoid this discoloration. It really take away from the look of the scooter.

 

A:You have 3 choices
 
 1. There is a type of anti blueing material you coatthe inside of the exhaust with. But can only be done on a new pipe. Cant be done if the pipe is used.
 
 2. Blue away. Removes the discoloration, but youwill have to do it over and over.
