2 stroke 50cc exhaust

[catadavidv]

Do you think a straight pipe will make it lose power?
Or any other good exhaust recommended?
This is what I was thinking about :

Got a transmission kit NARAKU (clutch belt varietor) coming tomorrow. Any other suggestion on what it should be the next upgrade? I can only use 50cc cylinder according to my country law you are not allowed to change the size of the cylinder, in a case of an accident the insurance does not cover anything if the cylinder is bigger than what is it wrote on manufacture papers.

Baotian bt49qt-20c Air cooled.

Is your scooter 2 stroke or 4 stroke? That model comes up as 4 stroke and that's a 4 stroke exhaust.

It won't make a lot of difference, as the four stroke exhausts are not as restricted as the two stroke ones.
These exhausts are more for cosmetics, and sound. Than performance.

A shit just saw what I sent. It's a 2 stroke. So as you guys say there is more restriction for 2 stroke and I guess I should forget about it. Any suggestion on what exhaust should I get for performance?

If you have a two stroke. There are loads of good pipes out there. Yasuni make some great pipes like the Z and R. They work well on a 50cc, or with a big bore kit.
This is worth a read www.pedparts.co.uk/blog/sports-exhaust-testing-50cc-and-70cc-sports-mopeds-part-one
They are more restricted. But are designed to be removed. Don't let that put you off.

Do you want stealthy
That looks like stock but gives more power than tecnigas silent pro malossi wild lion polini speed all give more speed and power .
Slight up jet on carb very little adjusting the cvt since the powerbands start at the same place as stock just runs higher

Or if you dont mind being louder than stock .
Go with Yasuni R or Z are very high Quality and will give you even more power and speed
Need up jet on carb
Stiffer clutch springs to start you up in the powerband at take off and lighter variator weights to have your cvt stay in the powerband .

This thing is already very loud for some reason. I do not mind beeing louder. Ahoi d I also change the carburetor? It is stock. I mean the whole scooter is stock only that it has a new cylinder droven only 400 km, that how I bought it.

[catadavidv]

It goes 62-65 on tacho. 100kg bodyweight. I guess it's working pretty normal. Open CDI

Then go Yasuni either R or Z
They are pipes that grow with you if you decide to upgrade further.
They give the most bang for the buck .

Just find out what jet is in the carb so you can get a couple between currrent size and 10% bigger say 3 6 and 9 % bigger .
You will need a couple sets of lighter weights say between 1/2 gram less than stock and 1 1/2 grams less than stock
Get some medium clutch springs that fit your clutch .
If not sure post pictures we will help you buy the right ones .

When you get the pipe there will be a couple of restrictions you will need to drill out so it flows to the full potential.

These are the restrictions in the Yasuni exhausts. They are not that hard to remove. Both held in by a couple of spot welds. Which you grind down.I

Agree with Zino. The Yasuni pipes really are fantastic. I have the Z and it is significantly louder than my stock pipe. I am very happy with the power gain. The R is the bigger version, so it's really about what you want to do and where you want to go with your mods. Great pipes though.

Also agree with Aeroxbud. The de-restrict is not terribly difficult. Take time and don't force anything.

Just relating my experience . Good luck with the build! ☺️
