Given the larger diameter tubing and shorter length, I suspect this muffler would enhance high-RPM flow, but may lose some mid-range. Similar to what happened with the Tyga when I installed it. This makes the lean low-end worse, while matching the too-rich factory top-end perfectly. I got a 5-8% power-increase with no re-jetting needed. Off-idle and mid-range had more stumbling. I added more low-end fuel by turning out pilot-screws 0.5 turns.
I don't understand why you refer to rpm-range used to acelerate
Well i remove the db killer, because i like how it sounds, but today i will try to ride with the db killer to see if the bike feels something good
also what does that work if you turn out the pilot screws?
