If you have a classic retro 150cc scooter like the pictures in the product page and want a performance exhaust, check this one out! it is low sweeping for the classic gy6 150 scooter. I will say in some cases the body will need to be modified so the exhaust doest hit on bumps (this is a reare case but worth mentioning) this will give you a boost in power and will be much louder than stock, but not to loud. check out the video for sound.
