I want to change to the exhaust pipe of my vespa thing 125 of year 91.
I have watched in this pagina and I like three exhaust pipes:
1.- Racing exhaust LEOVINCE PX80-150/Sprint/GTR/GT/Super/Vespa125-150
2.-Racing exhaust POLINI PX80-150 Sprint/GTR/GT/TS/Super/Vespa 125-150, with alu silencer
3.-Racing exhaust SIMONINI PX80-150, right, with carbon silencer, silencer l=200mm,d=50mm, chrome
I would like you said to me who goes better for my vespa.
What is the meaning of: Halter muss modifiziert werden
What modifications I need to make to mount anyone of these exhaust pipes???
Thank you very much
