I put a boost bottle on my shee when it was bone stock and actually noticed better throttle response on the lower end. Laugh if you all want but I did notice a difference. No more power just better response at low rpms. When I put my pipes on the bottle was in the way so it was bye bye for the bottle. If you do alot of slow trail riding or run mostly at lower rpms I would get one. If not dont waste your money. Shee's arent made for slow trail riding and low rpms anyway. It is a 2 stroke,so wind her ass out and save your money.The bottle gets a bad rap because people expect too much from it.
