The GMax Scooters exhaust is a new product, which combines everything that a 4-stroke Scooters rider could ever desire. Maximum power, muffled, unobtrusive sound, stainless steel / aluminium construction, great looks and 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. Supplied with all required mounting kit. **
