Exhaust "SITO Sport" Replica Vespa 50/90/100

Hello

Does anyone know if I can use the "SITO Sport" Replica Vespa 50/90/100 exhaust on a 1974 primavera?

I know that it states on the descrition that the exhaust is to be used with 50/90/100's but I was thinking because the 50 special is so similar to the PV that I still might be able to use it.

Cheers for anyone's reply.

 

 

Yes that will work.
