Hard to go wrong with Akrapovic for a standard mount exhaust. Personally, I like a low mounted exhaust for a few different reasons so I'd lean toward the Graves system. The SC and Austin look like they would be very loud. I don't like loud exhaust systems, track or street.
Also, that's a great looking bike. I wish they would sell the winter test version in the US, I think its the best looking version of the Gen5.
