Slip-On Series Muffler - Carbon FiberThis race inspired hexagonal muffler is made from beautifully crafted carbon fibre while the updated end cap is now made out of light weight titanium. The EC ECE type approved exhaust delivers an increase in both power and torque across the rev range. The use of titanium for the pipes and muffler inner parts creates an additional reduction in weight. When used with the link pipe, the ECU must be remapped.
