They are made in Italy and are very good quality if you are to believe what my mate has to say about them ( he has used their exhausts on previous bikes )
They appear to be the cannister and a joining pipe from what i can see on their site.
There is also another pipe available from them on the sites main page.
They have a dyno graph on their site and a short video of the RR8 on the dyno with one fitted
Why would anyone want to make there bike quiter......?
