Piaggio Typhoon 125 2T Parmakit/exhaust

Hello 

I’m working on a project on the Typhoon 125 2t 

I built the scooter using:

*parmakit 178cc

*crank BGM 110 55

*manifold mmw +Vforce4

*craborator mikuni 28

*variator Jcosta

* clutch dr pulley

I wanted to know witch exhaust do you recommend me to use with Parmakit and the list of products I wrote above?
