Hello everyone!
So i have a beta ark scooter air coled minarelli block.
The setup is:
Dr evo 70 cc cylinder
Motoofrce racing crank
17.5 dellorto-80 main jet
Polini hi speed variator
Top performance clutch and bell
Stock exhaust without restrict
It runs okay but desperate for a better exhaust.

I'm looking for a tuning exhaust but something good no leo vince zx and top nardo's. If someone had a similar setup and experience about other exhaust I would be very thankful.
In final product would like to have a lot of torque with the exhaust( power wheelies and good mid power).
