Genuine vespa t5 exhaust

[mikeveslam]

Just got myself another t5(Classic) not owned one for a while but had lots off them over the years.
The scooter is great and in nice std condition.
The only thing that let's it down is its new sito exhaust that is fitted to it.
In the past I have always fitted genuine std pipes to my t5 as they sound so much better and pull better low down than the sito.
There does not seem to be many std pipes around at the moment(I am trying to get one from shop in USA at the moment but it is a long shot)

So does anyone know where there are any going, new or second hand???(pref in uk)
Has anybody modified the sito, ie cut it open and put some baffles in it, if so what where the results
Or can any body advise on a better aftermarket pipe or expansion chamber for a std t5
Cheers thanks for reading
