OK So im still new on the 125 scene and wanted to know the answer to this quick question. I have the runner 125 (new shape so 4 banger) I dont have a prob with the performance or anything but would generaly like to find out if... a sports pipe such as a leo vinci (obviously a 125cc compatable model lol) will have any sort of advantages over the stock pipe? and if so will i need to change anything else aswell as the pipe?
tbh ALL the so called performance pipes make FUCK ALL power.. most loose power and are far too loud.. the stock item is banging altho ugly and heavy. only change it if you want it to sound like a pitbike
