straight pipes if to big or that dont have enough back pressure can mess up your valves. if you are running a very small diameter pipe and then it has a little bigger tip then i can see you being fine but i have seen stupid people mess up there cars and trucks with straight pipes and these chinese scooters are alot more finicky
