That was the first version of the Akra, a prototype version. Then they went ahead and made it ugly with the current hex type end caps.
My point was to show that the Akrapovic EVO pic was just a prototype conpared to what we have available for the 1098/1198/848.
If Termignoni decides to release a different type of exhaust system, hopefully it'll look something similar to the race version on Haga's bike!
