Exhaust Yasuni C21 (Aluminium)

Details
The Carrera exhausts from Yasuni are real high-end systems similar to Evolution, MK ProRace and MHR/MHR Team and should only be used in conjunction with 70cc Racing cylinders. 
The aluminium silencer comes equipped with the rubber seals known from C20; expansion chamber as well as bracket and silencer mount have been completely revised. 
The C21 provides great power at mid and higher revs. A real gem. 

Attention: since June 2008, the exhaust brackets come in a black matt finish. They are still made of steel, but the steel has now been treated using a patented process that makes the material heat resistant up to 600°C. This way, the brackets withstand environmental conditions over years and can also stand up to 200 hours of salt fog!!!
