How much faster will my 50cc suzuki ap50 go when i put a spors exhaust on it?

The only change you'll notice is more noise.

you'll go 12 mph instead of 11 mph.

Not sure why you're buying a sports exhaust for that silly thing, why not get a 125 (or bigger if you've passed your test), you'll be able to go 70 stock then.

Probably be slower as it would need re jetting, even then a 2mph gain would be tops.

dont bother,it will just make it "sound"faster

Even with a true expansion chamber exhaust, you won't get any more top-end speed... but you'll top out a lot faster.

With more power, the potential top speed will increase, instead of over reving the engine, think about a rear wheel sprocket with less teeth. To gear for say 40 mph instead of 35 mph, do this calculation: Number of teeth on existing rear sprocket * (35 / 40) = Number of teeth on new sprocket Example: Existing number = 36 teeth, so 36 * (35 / 40) = 31.5 teeth , so choose say 32 teeth

You will never notice the difference.If you want more power get a more powerful bike
