Among insiders, the Turbo Kit name is synonymous with peak performance. The X-Road Scooters exhaust is a new product, which combines everything a rider could ever desire. Maximum power, muffled, unobtrusive sound, stainless steel / aluminium construction, great looks - an outstanding value for money.The silencer is equipped with a silencer (Noise Killer). The snap ring securing is more advantageous than a conventional screw fastening. Screws vibrate, come loose and then you lose the Noise Killer. Fits on 50cc Hyosung GT125. 2-in-1 system.
