What is it you want in an exhaust. Standard with the servo removed gives most power without a remap as most cans lose out where Honda has excelled in setting up the bike, Arrow GP2 has the nicest note I've ever heard on a bike (without the baffle) but with the baffle fitted it sounds shit. Can't comment on any more just yet but I am currently waiting for a Yoshi R-77 to be delivered. I'll report back when it's here and fitted. Also the Arrow fitted was a bit of a pig to start due to the reduced back pressure. A Yoshi or Leo Vince or Akra would maybe be slightly better due to the serpent pipework to emulate a long secondary pipe before the can which gives more back pressure than a straight through pipe..
Was that without the remap then? If so I take it back. I was led to believe that standard was best without remapping
Without mapping it was same as standard ... The issue with aftermarket systems is fueling then runs lean and hence they loose low-mid grunt
