You will more than likely make it faster by gutting the exhaust,but I need to know a little more about the motor.Is it a 2-stroke or 4-stroke,what brand carbuerator is it?I can help if you give me more info on the scooter.You can e-mail me directly at ronaldslavik@Yahoo.com with the subject being your question.I will post my reply on here and send to you also. Ron Please don't gut your exhaust. It will most likely make it run worse, get you in trouble with the cops. To make it go faster mill the head or install a thinner head gasket might help or take your piston to a chain saw shop and get a more high performance piston. You may have to rejet your carburetor after you modify your motor. Yes it will help your scooter and you wont get introube withe the cops it will be the same as an Xcan. how you gut it is take out all of the pading and you can drill the outlet out 2 5/8in or 1/2in. you may have 2 cut the muffler in half then reweld it but dont back down do what ever it takes to gut it.
An improved flow of air and fuel mix will make the scooter faster. You can do this with an aftermarket exhaust.
No. Removing a restricter on a scooter's carb will make it faster but decrease mpg. If you are talking about a restrictor on the exhaust, then most likely you will increase mpg, but boy is it LOUD.
It will not really improve your top speed but it will give a better growl and have better acceleration and power on the hills.
but a engine in it
TO MAKE THIS FASTER YOU NEED TO BUY A NEW AIR FILTER AND EXHAUST PIPE. WWW.MONSTERSCOOTERPARTS.COM install a first class Johnson rod kit.

First if your fat go to the gym, second buy it a performance kit, third go to www.partsforscooters.com they have a wide variety of performance parts for scooters, dirtbikes, and minichoppers at low prices. it is a good website to order from i recommend it.if you are talking about a full size scooter you would have to get a CDI that has no rev limiter and remove restrictions in the variator and exhaust.that is how you do it cheaply, of course there are mods available to improve performance.

Yes it will make the scooter go faster, but you could run the chance of blowing parts in the moter if you do so
