From what I understand, a remap isn't absolutely necessary with a slip-on. I had a 2 bros slip-on on my 929. I used it stock, and with a map from dynojet for the 2 bros. Only difference was it smoothed out the throttle response a bit. The 929 has an abrupt on/off feel. For a full system, you'll need to remap. I upgraded to a full system and used a generic map at first. Then I got a custom map and it made a difference. All bikes are different, so even if a map was made for your bike + exhaust, it's still not going to be optimal, as it wasn't made for your particular bike.
