OK.... Here is a very easy fix for a bone stock 150cc GY6 Scooter. Just simply re-jet the thing. Main and Idle Jet...

Replace the Idle Jet with a 40
Replace the Main jet with a 108-112 roughly

Most of the 30 lb. boat anchor mufflers with the cheap aluminum wrap, and rivets on the ends could be cut off.... and use a short performance muffler welded on in its place.... You don't have to go loud to get performance.... Use a short muffler off a 250cc or larger engine.... with a larger outlet on the back than stock.

Don't need to make any other changes.....
