Dont have the dyno access to prove it, but recently put the pipe on my 2016 and we did not lose any power. I feel its made the motor a little more usable at lower rpms, below 3500 is where it begs for an upshift now as opposed to 4000 before, which was unexpected and nice. And power is definitely much more accessible throughout the rest of the tach.
At the same time I installed the exhaust I also did new chain and sprockets, dropping the rear from 46t to 45t. Super minimal change but perfect to slightly adjust the rpms in my most used gears/speed situations. Even with a sprocket change that drops torque slightly the bike feels more powerful and responsive. I am getting 55-65 MPG since the exhaust and sprocket install (but also ride above 7000ft 90% of the time which helps).
For sure a little louder but not obnoxious at all, I exclusively use it with the baffle in and think it sounds great. Now this is not the 5-holed disc baffle that fits in-between the muffler and collector pipe, which must be installed while installing the pipe on the bike, I do not run that one. I mean the baffle at the exhaust pipe outlet, which is removable with an allen key and pliers anytime, some may call it the 'quiet insert'. I run the 'quiet insert' baffle at the exhaust tip all the time.
Hope this helps
