Lets see... we can't count stock... that's only a placeholder....
so Eisenmann Sport ... then race (oops a bit loud!) back to sport again, then Akra, now this... that's not so bad! And they were all good systems.

Yes the valves are really effective , you virtually have a race or sport version at the flick of a switch. Closing off the valves gets rid of any drone at low RPM,(which is normally the killer with race systems) quietens it down some and changes the pitch a little which makes for nice round town driving but still retains a good throaty sound. Open the valves up and under load it sounds prodigious, and satisfies the hoon in all of us
