Not strictly Vespa but I've just bought an Indian 5 port barrel and note that there is no exhaust stub. Instead it had 2 threaded holes similar to a T5 but the port is smaller and the stud centres are closer. I don't think this is normal, anyone any experience of this? is there a suitable exhaust available or will I have to make up a flange and stub?
Before the inevitable 'what did you expect buying from India' (be gentle Muttley McLadd), it has to be said that quality wise it is VERY well finished, the ports are all tidy unlike a lot of SR style barrels I've seen and at £25 including head and piston I thought it worth a punt
Cheers
