Maxiscoot and MXS Racing are proud to present to you the result of many years of development: the exhaust MXS GP90 at a very good price! Developed specifically for MXS GP90 cylinders, this exhaust MXS GP90 is a model "Hyper Racing" very "upscale". His body is handcrafted steel sheets "rolled-welded" varnish, finished with a aluminum silencer. Its volumes receive special attention to match perfectly cylinders "GP90" in the same series. Based on tests that we carried out this exhaust is also very efficient in combination with other cylinders "Hyper Racing" from 86cc to 95cc. Furthermore the fastening flange 4 screw can also be used with only two bolts for regular cylinder kits with 2 bolt exhaust.
