they are expensive though, but if you found a used one on ebay it might be ok

[onamission1989]

Changing the exhaust on a 4 stroke 50cc would make next to no difference in performance. Those performance exhausts are only for 2 strokes.

No- that's a two stroke exhaust, you can tell by the shape. The bulge in the middle is the expansion chamber, it's designed to create back pressure pulses to improve the power. It might fit on a four stroke, but there would be no performance benefit. Four strokes generally want a nice straight, constant diameter pipe with an unrestrictive silencer on the end.

I wouldn't mind putting a better exhaust on my 2-stroke scooter but havn't found anything that looks like it will fit.

doese anyone know if you can get a sport exsaust for a BAOTAN BT50QT? its a 2 stroke 50cc and its brand new

chees all

[BillyGreen1973]

Are you sure its 2 stroke, I thought all new Baotians were 4 stroke due to the law changes in China

You can use Honda XR50 pipes to for tircking your exhaust. They are 4 storkes, but the problem is they have a different mating flange and might not fit the profile of a scooter.

yea sorry i ment 4 stroke

and that link doesent work

would putting a new exsaust on there improve its performance, if not is there anything ells i can do to increase the speed

[chcknugget]

If you highlight the whole link (onto the next line) and put it in the explorer bar it will work. The link in my previous post was just too long for the forum.

Also, you cannot just put on an exhaust by itself. You need to rejet your carburetor to adjust for the new fuel flow.

Just search "xr50 exhaust" on ebay... The mounting flange on their pipes is very similar, but rotated about 45 degrees.
