SIP racing exhaust manifold for Piaggio/ Gilera 125/180cc 2-stroke maxi-scooters.

Made using stainless steel, designed to replace the original Piaggio manifold. Cutting edge production has ensured this manifold has reduced turbulance and the internal diameter has been increased to 35mm. The increased diameter tube increases power upto 1hp. 

Maximum performance can be achieved by matching the diameter of the exhaust port with this manifold.

2x gaskets included
