Leo Vince exhaust.

[outlaw]

Hi guys,
New user and new (I hope!) question.
I'm looking at a Leo Vince 4 road exhaust for my Vespa GT125 (20005 carb model) but have now been told to save my money 'cos it'll actually REDUCE the performance of my bike.
So: is this true? does anybody have one on a GT125? if I fit one will it need re-jetting or dyno-ing?
Thanks in advance to a question which no-one thus far seems able to answer.

There's a 10 page thread running here...

I haven't read it but you might get some of the answers you need.

Thank you sir!
Edit: Just read it and it's a load of nonsense about nothing really. I just can't seem to find ANYBODY who's actually fitted one to a GT125 and can give an honest appraisal.
