We offer you here the Slip-On exhaust system from Giannelli for the Yamaha WR 125. Gianelli is characterized by many years of experience in the field of exhaust systems. The use of aluminium makes the sound more pithy and cracking than carbon systems. You can increase the power of your car with the system by about 1 HP as usual, whereby the power curve shifts to the lower speed range. Of course we deliver the exhaust system with EC type approval. You will also find a suitable catalytic converter in our shop.
