Looking at geting this for my new engine build (Piaggio zip ac 05 plate) I see the exhaust stubs are removible ? Well can you buy different ones to match them to different kits Stage 6 race 70cc... Or do you do what you do when opening a exhaust port on a kit ? can you port a exhaust stub ? Sorry if I don't make any sence.
no, you port the kit to match the stub. NEVER mod a stub. it will just leak or break. certian kits have replacment stubs avalable... but not this one. theres no need. if your using the correct type of kit for the pipe you wish to use the exhaust port should be pritty similar. its only when you have a multi application kit (like the olive fitment exhausts aka pm/leo vince/other shit like that) they have a taperd exit/fitting for the exhaust... mid race kits shoudlent have this.
